This is a great set of old brass furniture casters. They are the platform style, where the platform of each caster is screwed to the bottom of the leg. Each wheel and yoke are brass. The platform and stem are cast iron.
Each brass wheel measures 1 1/4 inches in diameter. From the platform to the floor is 1 3/4 inches.
The platforms measure 1 3/8 inches in diameter, and each one is mounted to a leg with three screws. The stems are 7/8 inch long and 1/2 inch thick.
This set is not only good looking, but the wheels can withstand a great deal of weight.
