Slim base adjustable leveling feet provide a Ø 40 mm base diameter that sits between the Ø 30 mm standard base and the Ø 50 mm wide base. More floor contact than standard, less visible overhang than wide. At 12 mm base height, the profile is lower than standard (18 to 19 mm) but taller than low-profile (9 mm). Static load capacity: 80 kg per foot.

The leveling foot range offers Ø 20, 25, 30, 45, and 50 mm bases. But what if your furniture legs are 35 to 45 mm in diameter and none of those standard sizes fits the proportion? A Ø 30 base is too narrow and sits visibly recessed under the leg. A Ø 50 base extends beyond the leg edge. Slim base adjustable leveling feet fill this gap with a Ø 40 mm base that matches the leg proportion on mid-size furniture without the overhang of a wider base or the undersized appearance of a narrower one.
Ø 40 mm PA base at 12 mm height. Zinc-plated steel M8 threaded rod at 20 mm. Static load capacity: 80 kg per foot. Slim base adjustable leveling feet are 40 mm base adjustable leveling feet for furniture where the standard sizes are either too small or too large. Black. Sold individually.
Slim base adjustable leveling feet are currently available in one configuration that fills the gap between the Ø 30 and Ø 50 mm bases.
Base height: 12 mm. Static load: 80 kg per foot (320 kg on four legs). Weight: 20.4 g. PA body + Fe HDG rod. Black. Compatible with M8 round, square, and rectangular threaded inserts.
Smaller: Low-Profile Ø 30 mm or Ultra-Low Profile Ø 25 mm. Larger: Wide-Base Ø 50 mm. More threads: Standard Base Ø 30/45 mm (M6 to M12). For custom slim base configurations, contact Business Solutions.
Slim base adjustable leveling feet fill a specific gap in the base diameter lineup. Here is how every base diameter compares for floor contact area and typical furniture leg match.
314 to 707 mm² contact. For legs under 35 mm. Low-profile and standard compact bases.
1,257 mm² contact. For legs 35 to 45 mm. The proportional mid-size option.
1,590 to 1,964 mm² contact. For legs 45 mm+ or maximum stability needs.
The Ø 40 mm base provides 78% more floor contact than the Ø 30 mm base. This additional contact area improves stability and reduces floor pressure without the visual bulk of the Ø 50 mm wide base. Slim base leveling feet M8 that match mid-size furniture legs proportionally. On a table with 40 mm square legs, the Ø 40 base sits flush with the leg width, creating a clean, proportional appearance at each corner.
Slim base adjustable leveling feet have a 12 mm base height. This positions them between the low-profile range (6 to 9 mm) and the standard base (18 to 19 mm). The 12 mm height provides moderate clearance between the floor and the tube end while keeping the foot less visible than a full standard base.
Ultra-low profile: 6 mm. Low-profile: 9 mm. Slim base: 12 mm. Wide base: 11 mm. Standard base Ø 30: 18 mm. Standard base Ø 45: 19 mm. The slim base at 12 mm provides enough height for moderate floor clearance and practical adjustment access, without the full protrusion of a standard base. On furniture viewed from standing height, 12 mm is less noticeable than 18 mm but more visible than 6 or 9 mm.
When the furniture needs more base height than low-profile (9 mm) for stability or adjustment access, but the full 18 to 19 mm of standard is too visible. When the Ø 40 mm diameter matches the leg size and the 12 mm height complements the design without excessive protrusion. Mid-size adjustable leveling feet that provide a balanced, proportional foot profile on mid-size furniture.
The same leveling function as every foot in the range, at the mid-size base diameter. The National Wood Flooring Association (NWFA) recommends protective contact surfaces on all furniture legs, and slim base adjustable leveling feet provide a PA contact surface proportional to mid-size furniture legs.
The primary advantage. On furniture with 40 mm square tube legs, a Ø 40 base sits flush with the leg edges. No visible overhang. No recessed appearance. The foot looks like a natural extension of the leg rather than an afterthought accessory. Slim base adjustable leveling feet provide the proportional match that the standard sizes miss for this specific leg diameter range. Medium base leveling feet furniture designers choose when proportion matters.
With 78% more floor contact area than the Ø 30 base, the slim base provides better load distribution and more resistance to tipping. For furniture that is too heavy for a Ø 30 base to feel stable but does not need the full Ø 50 wide base, slim base adjustable leveling feet fill the gap. Unlike leaving mid-size furniture on mismatched bases, the Ø 40 provides right-sized stability.
Same independent height adjustment as all leveling feet. Turn each foot to raise or lower that corner until the furniture sits level. The M8 thread at 80 kg per foot handles standard furniture weight. The 20 mm rod provides fine to moderate adjustment for typical residential and commercial floor conditions.
The PA base provides smooth, non-scratching floor contact at the Ø 40 mm diameter. More contact area than Ø 30 means more vibration dampening at each leg. On hard floors, the larger base absorbs more contact noise than a narrower foot, contributing to a quieter environment in offices, conference rooms, and dining spaces.
Same installation as every other leveling foot. The Ø 40 mm base does not change the process. Screw the foot into the M8 threaded insert, set the furniture on the floor, and adjust the height at each leg.
Because all leveling feet share the same M-thread interface, you can use slim base adjustable leveling feet on some legs and a different style on others. On a conference table with visible front legs and hidden back legs, use slim base on the front for proportional appearance and standard base on the back for longer rod adjustment range. Both M8 feet screw into the same threaded inserts.
This flexibility is particularly useful when the table sits on a floor that slopes from front to back. The front legs may only need 20 mm of adjustment (slim base range), while the back legs may need 43 mm or more (standard base range). Mixing profiles gives you proportional appearance where it matters and extended adjustment where it is needed. The universal M8 thread makes this seamless.
For furniture manufacturers using 40 × 40 mm square tube legs (one of the most common commercial specifications), slim base adjustable leveling feet are the proportional match. The Ø 40 base sits flush with the 40 mm leg, creating a clean transition from leg to foot. No overhang, no visual gap. Specify alongside M8 square threaded inserts for the complete leveling system.
On projects where the leg diameter varies across different furniture pieces in the same space (tables with 40 mm legs, side tables with 30 mm legs), specify slim base on the 40 mm furniture and low-profile Ø 30 on the 30 mm furniture. Each foot matches its furniture’s proportion while sharing the same M8 thread for inventory simplicity. For production quantities, visit Business Solutions.
The Ø 40 mm base provides 1,257 mm² of floor contact. On a four-legged table with slim base adjustable leveling feet, the total floor contact across all four feet is 5,028 mm². This distributes the table’s weight broadly enough to prevent indentation on standard hardwood, engineered wood, and luxury vinyl floors under normal furniture loads.
At 80 kg per foot on M8, a four-legged table supports 320 kg total. Dividing 80 kg across the 1,257 mm² base gives 0.064 kg/mm² of floor pressure. This is lower than the Ø 30 base (0.113 kg/mm² at 80 kg) and higher than the Ø 50 base (0.041 kg/mm² at 80 kg). For most standard residential and commercial flooring materials, this pressure level does not cause visible indentation under normal furniture weight. On softer floors like cork or thin luxury vinyl over soft underlayment, the Ø 50 wide base provides lower pressure if indentation is a specific concern.
Same two-material construction as all standard PA leveling feet. PA body for floor contact and load distribution. Zinc-plated steel rod for the threaded connection.
The Ø 40 mm PA base at 12 mm height provides 1,257 mm² of floor contact. PA resists UV, chemicals, moisture, abrasion, and impact. The smooth PA base surface provides quiet, non-scratching contact on all standard hard floor surfaces including hardwood, tile, and concrete. At 20.4 g total weight, the slim base foot is lighter than the wide base (27.5 to 35.2 g) and heavier than the low-profile Ø 30 (15.5 to 41.9 g depending on rod length).
M8 thread, 20 mm rod length. Zinc plating provides corrosion resistance for standard indoor use. For stainless steel rods in corrosive environments, see stainless steel rod leveling feet.
Standard base Ø 30 has less floor contact (707 mm² vs. 1,257 mm²) but offers M6, M8, and M10 threads with rods up to 63 mm. Choose Ø 30 for more thread and length flexibility. Choose slim base for better proportion on 35 to 45 mm legs.
Standard base Ø 45 has more floor contact (1,590 mm²) and offers M8, M10, M12 with rods up to 110 mm. Choose Ø 45 for heavier loads or more adjustment. Choose slim base when Ø 45 is too large for the leg proportion.
Wide-base Ø 50 provides maximum stability and contact area (1,964 mm²). On furniture with 40 mm legs, the 50 mm base extends 5 mm beyond each side. Slim base sits flush at 40 mm. Choose wide for maximum stability. Choose slim for proportional fit.
Restaurant and office tables with 40 × 40 mm square tube legs. Conference tables and meeting room furniture with mid-size round tube legs. Retail display fixtures where the leveling foot must match the fixture’s proportions. In commercial furniture manufacturing, the Ø 40 base matches the 40 × 40 mm square tube that is one of the most common commercial furniture leg specifications. Slim base adjustable leveling feet sit flush with the leg edge on this tubing, creating a finished appearance that customers and guests notice. In open-plan offices with dozens of identical desks, the consistent proportional fit across every desk creates a clean, professional visual across the entire floor. Available for bulk orders. For commercial pricing, visit Business Solutions.
Dining tables, home office desks, and kitchen tables with mid-size tube legs. On residential furniture where the homeowner notices the details, a leveling foot that matches the leg diameter looks intentional rather than like a generic add-on. The proportional fit communicates quality. A mismatched foot (too small or too large) communicates compromise. For furniture with round, square, or rectangular threaded inserts with M8 threads and 35 to 45 mm legs, slim base adjustable leveling feet provide the best proportional fit available in the leveling foot range.
Check periodically that the foot is tight in the threaded insert and the furniture remains level. The 12 mm base is moderately visible during inspections, easier to see than ultra-low or low-profile but less prominent than standard. Re-tighten by hand if loosened by vibration or adjustment. After relocating furniture, readjust all feet for the new floor conditions. On furniture that moves between rooms or locations, the slim base Ø 40 provides stable contact on the new surface without the excessive overhang that a wide base creates on narrow legs.
Slim base adjustable leveling feet are sold individually for single-foot replacement without disrupting the other legs. The PA base does not degrade from standard cleaning chemicals, UV exposure, moisture, or normal wear. If the zinc plating on the rod shows corrosion, replace the foot or switch to stainless steel rod leveling feet. As a single-SKU product, slim base adjustable leveling feet simplify inventory: one part number for every leg on every piece of furniture that uses 40 mm legs with M8 inserts. No size selection confusion on the production floor or in the maintenance supply closet.
Standard Base Ø 30/45 mm: M6 to M12, rods to 110 mm.
Wide-Base Ø 50 mm: maximum contact area.

Choose slim base when Ø 30 mm does not provide enough floor contact area for your furniture’s weight, but Ø 50 mm would extend too far beyond the leg and look disproportionate. The Ø 40 mm base provides 1,257 mm² of floor contact, which is 78% more than Ø 30 (707 mm²) but 36% less than Ø 50 (1,964 mm²). For furniture legs in the 35 to 45 mm diameter range, the Ø 40 base matches the leg proportion well.
M8 at 80 kg per foot covers the majority of furniture that specifies the Ø 40 mm base. For M10 (120 kg) or M12 (150 kg), standard base Ø 45 mm provides those threads with a slightly larger base. For M6, standard base Ø 30 mm is available. For custom slim base thread options, contact Business Solutions.
Standard base: 18 to 19 mm. Slim base: 12 mm. Low-profile: 9 mm. Ultra-low profile: 6 mm. The slim base sits in the middle of the height range, providing moderate clearance between the floor and the tube end without the full visibility of a standard base.
Yes. The M8 thread is the same across all leveling feet. An M8 slim base foot screws into any M8 round, square, or rectangular threaded insert. You can swap between slim base, standard, low-profile, or any other M8 leveling foot without changing the insert.
20 mm provides fine to moderate adjustment for floors with minor to moderate unevenness. For most residential and commercial floors, 20 mm is adequate. If your floor has significant unevenness, use standard base (rods up to 110 mm) or low-profile (rods up to 50 mm) for more range.
