Snap-In Tube Chair Leg Glide
A replacement glide foot that plugs into round tubular chair and table legs with a 19–21.5 mm inside diameter, such as 7/8 in (22.2 mm) or 25 mm OD tube. It replaces the broken or worn-out original insert. Four slotted fingers with 45° barb ridges (21.6 mm across the ridges) squeeze down to grip the tube wall. It sits on a 34 mm, 5 mm-thick foot, and you can stick a 25–30 mm felt pad under it for hard floors.
