One configuration: 20 × 30 mm rectangular tube, grey, flat PA contact, one screw, 12.8 g. This is the only end glide in the range designed for rectangular tube profiles.

For round tube ends (Ø 28): round tube end glides. For oval tube ends: oval tube end glides. For round tube mid-runner: rectangular base glides. For custom tube sizes, contact Business Solutions.

How Rectangular Tube End Glides Work

Rectangular tube end sled base glides slide over the open end of the rectangular runner tube. The internal cavity matches the 20 × 30 mm tube profile. The tube inserts into the cavity, and one screw through the side locks the end glide in position. The flat PA base extends beyond the tube end, providing floor contact at the runner’s terminal point.

The rectangular cavity provides a more secure fit than a round cavity would on a rectangular tube because the flat internal walls press against the flat tube sides. There is no rotational freedom as there would be with a round tube in a round cavity. The end glide locks into one orientation and stays there.

Why Rectangular Tube Ends Need Protection

The open end of a rectangular tube has four sharp edges (top, bottom, left, right) that can scratch floors. The thin tube walls create a narrow contact line that concentrates the furniture weight. The open tube collects dust, dirt, and moisture. Rectangular tube end sled base glides solve all three problems: they cover the sharp edges, distribute the contact across the broader PA base, and seal the tube opening against debris.

On sled furniture where the rectangular runner extends forward past the front legs, the runner end drags across the floor every time the chair is pushed in. Without an end glide, the four sharp edges of the rectangular tube create visible scratch lines on hardwood, luxury vinyl, and polished concrete. The PA end cap replaces these sharp edges with a smooth, flat PA surface that slides across the floor without marking it.

20 × 30 mm Rectangular Tube Sled Furniture

The 20 × 30 mm rectangular tube profile is used on sled furniture where the designer chose a rectangular cross-section for aesthetic or structural reasons. The rectangular profile provides a different visual line than round tubing, and the wider 30 mm dimension can provide more structural rigidity in one direction. This tube size is common on European-designed commercial and institutional sled furniture.

Rectangular tube sled furniture uses the same cantilever or U-frame design as round tube sled furniture. The runners extend horizontally along the floor, bend upward into risers, and support the seat. The only difference is the tube cross-section. Rectangular tube end sled base glides provide the same end-sealing and floor protection function for rectangular tubes that round tube end glides provide for round tubes.

Flat PA Contact (No Pad Slot)

This end glide uses flat PA floor contact without a pad slot. The PA surface provides smooth, non-scratching contact suitable for most standard hard floor surfaces. For scratch-sensitive floors where a PA6 pad is preferred, apply a self-adhesive PA6 pad to the flat PA base. The adhesive pad adds a PA6 layer to the existing PA surface for enhanced floor protection on premium hardwood and luxury vinyl.

The round tube end glide (Ø 28) has a built-in pad slot. The rectangular tube end glide does not because the smaller base dimensions (39 mm length) leave less room for a recessed pad slot while maintaining adequate wall thickness around the tube cavity. The flat PA surface is the standard floor contact for this end glide configuration.

How to Install Rectangular Tube End Sled Base Glides

Single-screw installation. The end glide slides onto the rectangular tube end and is secured with one screw through the side.

What Rectangular Tube End Sled Base Glides Solve

Floor protection, edge coverage, and tube sealing at the endpoint of 20 × 30 mm rectangular tube sled runners. The National Wood Flooring Association (NWFA) recommends protective contact on all furniture contact points, and the open rectangular tube end is a contact point with four sharp edges that needs protection.

Floor Surface Compatibility

Materials

PA (polyamide) body. The same engineering polymer used across all sled base glides, furniture glides, leveling feet, and tube plugs in the catalog. PA provides the structural rigidity needed for the end cap enclosure function, the abrasion resistance for floor contact, and the impact resistance for the tube end position that takes the initial contact when furniture is pushed forward.

Comparing End Glides Across the Range

Confirming the 20 × 30 mm Rectangular Tube

Measure the outside dimensions of the runner tube at the end. If it reads approximately 20 × 30 mm (about 3/4 × 1-3/16 inches), this is the correct end glide. The internal cavity is shaped specifically for this tube cross-section. A round tube will not fit (use round tube end glides for Ø 28 round). An oval tube may look similar but has curved sides rather than flat sides (use oval tube end glides for oval profiles).

The tube wall thickness must be between 1.5 and 2 mm for the internal cavity to fit properly. Measure the wall at the tube end with calipers. If the wall is thinner than 1.5 mm, the end glide may fit loosely on the tube. If thicker than 2 mm, the tube may not slide into the cavity. Most commercial rectangular tube sled furniture uses wall thicknesses within this range.

Rectangular vs. Round vs. Oval Tube Profiles

Sled furniture uses three tube profile types, and each has its own end glide. The tube profile is a design choice made by the furniture manufacturer. All three profiles serve the same structural purpose (supporting the seat on horizontal runners), but they differ in visual appearance, structural properties, and the end glide required.

Four Sharp Edges: Why Rectangular Tubes Need End Glides

A cut rectangular tube end has four sharp edges where the flat sides meet at the corners. These edges are sharper and more concentrated than the single continuous edge on a round tube end. When the furniture is pushed forward, all four edges can scrape the floor simultaneously, creating parallel scratch lines that are distinctive and difficult to repair. Rectangular tube end sled base glides cover all four edges with the smooth PA cap.

On carpet, the four sharp corners can catch and tear carpet fibers more aggressively than a round tube edge because the corners concentrate the snagging force at four discrete points. The PA end cap rounds over these corners and provides a smooth surface that glides over carpet without catching. On hard floors, the PA base replaces the four-edge contact with a single flat PA contact surface that distributes weight evenly.

Tube Sealing on Rectangular Tubes

Open rectangular tube ends collect debris more readily than round tube ends because the flat bottom of the rectangular profile sits flush with the floor when the runner contacts the ground. Dirt, dust, food particles, and cleaning solution flow directly into the open end along the flat bottom surface. Rectangular tube end sled base glides seal this opening, preventing internal debris accumulation and the corrosion that trapped moisture causes inside steel tubes over time.

In cafeterias, commercial kitchens, and healthcare environments where floors are mopped or cleaned daily, the sealed tube end is especially important. Water that enters an open rectangular tube end sits on the flat bottom of the tube interior and does not drain out easily because the rectangular cross-section traps liquid more effectively than a round tube where water can run along the curved bottom and out the opposite end.

How Many End Glides Do I Need?

Count the open rectangular tube ends on your furniture that contact the floor or need sealing. Most sled chairs have 2 runner ends at floor level (the forward-facing ends). Some designs have 4 exposed ends (front and rear of each runner). Not all tube ends need floor-contact end glides if they are positioned above the floor, but all open tube ends benefit from sealing regardless of floor contact.

Rectangular tube end sled base glides are sold individually. For a fleet of 30 chairs with 2 floor-contact ends each, order 60 end glides plus a 10% spare stock. Keep spare end glides in maintenance stock alongside any mid-runner glides used on the straight sections of the same furniture.

Wear Patterns and Replacement

The flat PA base wears from floor contact when the furniture is pushed forward or repositioned. On chairs that are pushed under tables after each use, the end glide base wears from the forward-dragging contact. The wear pattern is typically uneven, with more wear on the leading edge (the side that contacts the floor first during a push) and less on the trailing edge.

When the PA base has worn unevenly or thin enough that the tube edge is close to contacting the floor through the worn PA, replace the end glide. Check the screw for tightness during each inspection. Rectangular tube end sled base glides are sold individually. Replace one at a time as needed, or replace all end glides on a chair simultaneously for even floor contact.

Specifying Rectangular Tube End Sled Base Glides for Projects

For furniture manufacturers producing sled furniture with 20 × 30 mm rectangular tube runners, include rectangular tube end sled base glides in the bill of materials for all furniture with open tube ends. The end glides seal the tubes and protect the floor at the runner endpoints. Include alongside any mid-runner glides specified for the straight sections.

For facility managers retrofitting existing furniture, rectangular tube end sled base glides are often added after discovering that the open tube ends are scratching the floor or collecting debris. The retrofit is simple: slide the end glide over the tube end and drive one screw. For production quantities, visit Business Solutions.
