Though these brass casters are available in a polished brass, antique nickel or weathered bronze finish, an exact match to your hardware finish is not essential since casters are not highly visible on most furniture.
All have turned brass wheels and polished treads, cast and polished brass yokes, and steel axle pins. Size given for each item is approximate wheel diameter.
The stem casters have a steel swivel post (stem) that seats 15/16" into a 1/4" hole in the leg.
The rosette casters have a 1 1/16" dia. polished brass mounting plate (1/8" thick), which uses three screws to attach to a leg bottom. The 1/4" steel swivel post helps mitigate racking.
The cup casters have brass swivel posts and tapered cups, which are secured to the leg with three screws. The inside diameter of the cup opening is the same as the wheel diameter.
Prices given are per caster; screws not included.
