Nail-on furniture glides (chair glides): base diameter and length under head — Essentra part sizes — dimension sheet
Source: Xem Studio, https://xemstudio.com/objects/furniture-glides-nail-on/  (sheet CC BY 4.0)
Basis: Essentra Components' nail-on glide catalog page: part number, base diameter and length under head, as printed (inch; mm is inch x 25.4)
Catalog version: 2026-10-20

Sizes: see table below
- Base diameter is the pad that rests on the floor and 'length under head' is the page's term for the dimension under the head of the glide (the nail / shank length); the page prints no overall height, nail diameter or nail length, so those are not given.
- The page lists 0.622, 0.752, 0.875 and 1 in glides in two variants each (A and B suffix, same dimensions) and five more sizes from 0.750 to 1.460 in with a 0.709 in length. Sellers also sell 3/4 in, 7/8 in and 1 in round nail-on glides (Zoro and Home Depot list the 3/4 in size with a rubber cushion bonded to a nylon base); only the Essentra rows are shown because only they print a second dimension.
- No standard governs furniture glides; sizes are by seller. Screw-in glides and levelers print different dimensions (stem thread, base) and are not covered by this page.
- No file: the base profile and nail are not published as numbers in the source read, so a model would be invented.
