Outwater 4-Pack 2-3/8-in Nylon Swivel Caster and 3/4-in Round Tube Insert Kit (2 with Brake)

Complete kit includes 4 swivel casters (2 with front foot brake, 2 without) and 4 double star threaded tube inserts; the 5/16-18 insert thread matches the caster stem.

Inserts fit 3/4-inch outside diameter round steel tubing with a 16 or 18 gauge wall; not designed for iron pipe.

Double star design sets deep inside the tube and grips the wall, so inserts stay in place over thresholds, cords and uneven floors; external edges fit flush with the tube for a clean, finished look.

2-3/8-inch Nylon 6 hooded twin wheel caster with 5/16-18 x 1-inch threaded stem, 2-11/16-inch mounting height (3-13/16-inch overall height including stem) and 2-3/16-inch swivel radius (2-7/8-inch on brake casters).

Load capacity of 100 lbs per caster (400 lbs for the set of 4).

Non-marring Nylon 6 wheels resist water, oil and mild chemicals and roll smoothly on hard floors and low-pile carpet; black nylon hood and wheels with a zinc finish stem.

Front foot brake locks the caster to keep the piece from rolling when parked.

Inserts are heat treated carbon steel with black oxide wings and a zinc plated base.

Well suited for tubular steel chairs, tables, carts and other light to medium duty furniture.
