Outwater 4-Pack 2-1/2-in Rubber Swivel Caster and 1-1/2-in Round Tube Insert Kit

Complete kit includes 4 swivel casters and 4 double star threaded tube inserts; the 3/8-16 insert thread matches the caster stem.

Inserts fit 1-1/2-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.

2-1/2-inch soft rubber single wheel caster with 3/8-16 x 1-inch threaded stem, 3-1/16-inch mounting height (4-1/8-inch overall height including stem) and 2-3/16-inch swivel radius.

Load capacity of 80 lbs per caster (320 lbs for the set of 4).

Soft rubber wheel gives an easy, quiet roll and a cushioned ride, resists chemicals, water and steam and rejects floor debris; nickel finish with a single ball bearing raceway and self-lubricating bearings.

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

Well suited for tubular steel furniture, small displays, rolling racks and carts.
