A leg that meets the floor at an angle instead of straight down leaves a flat plug tilted and riding on one edge. These press into the tube at the same angle as the leg, so the base lands flat and level with no shimming. Two angles cover splayed and raked chairs, stools, and tables. Fits Ø 20 and 22 mm tube.
We make this size in production runs, so there is none on the shelf today. Tell us how many you would want and you go on the list for it. When enough people ask for a size, we run it, and the people who asked hear about it first.
We stock a limited range of tube sizes and wall thicknesses. Tell us the size you need and we will confirm availability and pricing by email.

Standard flat head plugs assume the leg meets the floor straight down. Many chairs, stools, and tables do not. When furniture legs splay outward or rake backward, a flat plug sits at an angle to the floor: one edge digs in, the other lifts off, and the plug wears unevenly, wobbles, and scratches. Angled round tube plugs solve this by building the angle correction into the plug itself. The body press-fits inside the tube at the same angle as the leg, so the flat base sits level on the floor. Full base contact. No wobble. No edge digging. No uneven wear. Also referred to as splayed leg tube caps, angle tube inserts, or round tube plugs for angled legs.
Same PE construction and flexible ribbed body as the flat head range. Same press-fit installation. The only difference is the geometry: the head is cut at a fixed angle (9° or 22°) relative to the tube axis. Angled round tube plugs are tube plugs for angled legs on any furniture with splayed, raked, or tilted hollow round legs. 2 diameters: Ø 20 and Ø 22 mm. Wall thickness 1.5 to 2 mm. Black and grey.
Three measurements instead of two. Angled round tube plugs require the standard outside diameter and wall thickness, plus the angle at which the leg meets the floor.
Use calipers or a ruler across the widest point of the tube opening. Outside edge to outside edge. Angled round tube plugs are available in Ø 20 and Ø 22 mm.
Use calipers at the tube end, or calculate: (OD minus ID) / 2. Both sizes require 1.5 to 2 mm wall for the ribs to grip properly.
Place a digital angle finder on the leg and read the tilt from vertical. A leg that tilts 9° from vertical needs the 9° plug. A leg that tilts 20° to 24° from vertical needs the 22° plug. If your reading falls between 9° and 22°, choose the closer value.
Same press-fit mechanism as all our tube plugs, with one extra step: rotational alignment. The angled base must face the correct direction relative to the leg’s tilt. Angled round tube plugs press in by hand at 1.5 to 2 mm wall thickness. A rubber mallet provides extra seating force if needed.
The specific problem of angled legs meeting flat floors. The National Wood Flooring Association (NWFA) recommends protective contact surfaces on all furniture legs, and these plugs ensure that the entire base contacts the floor evenly instead of concentrating pressure at one edge.
The primary function. When a standard flat plug goes on a tilted leg, only one edge touches the floor. That single line of contact concentrates all the weight, digs into the floor finish, and creates a pivot point. Angled round tube plugs correct the tilt so the entire flat base meets the floor. Weight distributes evenly. No edge digging. No pivot. These are the tilted leg tube plugs that eliminate the geometry problem at the source. Angled furniture leg plugs that match the leg to the floor.
A flat plug on a tilted leg creates a sharp line of contact that scratches hardwood, gouges vinyl, and wears through laminate. Angled round tube plugs spread that contact across the full base diameter. Less pressure per square millimeter means less damage. Unlike leaving metal edges unprotected, the flat PE base provides a smooth, broad contact surface. For additional scratch protection on sensitive floors, apply a round self-adhesive furniture pad to the flat base.
A plug that only contacts the floor at one edge creates a pivot. The chair rocks. It tips. It makes noise every time someone shifts their weight. Angled round tube plugs eliminate the pivot by providing full base contact. The chair sits stable and flat. No rocking, no tipping, no metallic scraping at the pivot edge. Splayed leg tube end plugs that turn unstable seating into stable seating.
Same sealed end as every other plug in the range. The angled geometry does not compromise the seal. Moisture, debris, and insects are kept out of the tube interior. Angled round tube plugs protect the tube and correct the floor contact angle at the same time.
Every variant uses the same internal ribbed PE body. The head determines floor behavior, appearance, and specialized function.

The angle depends on how far the leg tilts from vertical. A chair with slightly splayed legs typically needs 9°. A stool or table with aggressively raked legs typically needs 22°. Measure by placing a digital angle finder on the leg and reading the tilt from vertical. If you are between the two values, choose the closer angle. A 9° plug on a 22° leg will leave one edge lifted. A 22° plug on a 9° leg will rock the opposite direction.
The angled base is flat PE, the same material as standard flat head plugs. It provides basic floor contact but not dedicated scratch protection. For angled legs on scratch-sensitive floors, install angled round tube plugs and apply a round self-adhesive furniture pad to the flat base for PA6 floor protection.
Almost. Ø 22 mm is available in both 9° and 22°. Ø 20 mm is available in 22° only. All sizes come in black and grey.
You can, but the plug will sit at the leg angle instead of flat on the floor. Only one edge of the plug contacts the floor, which creates a pivot point, concentrates wear, and can scratch floors. Angled round tube plugs eliminate this problem by compensating for the leg tilt so the full base contacts the floor.
For custom angles, contact us through Business Solutions. Custom molds are possible with minimum order quantities. For angles close to 9° or 22°, the standard plugs often work well enough because the PE base has slight flex that accommodates minor deviations.
