Hammer Caster Stretcher Caster 915mk RB 100mm

I am selling this because it did not fit when I tried to purchase and install it.

Features: The large ball race diameter (P.C.D.) of the swivel section and the adoption of wide wheels (W32) provide outstanding swivel performance and running stability.
The new mechanism developed with the excellent technology and know-how of Hammer Caster, along with a high-grade chrome plating finish, makes it ideal for equipment in hotels, hospitals, offices, and other places where robustness and elegance are required.
Note: The total lock is a stopper mechanism that can simultaneously lock the swivel and the wheels.
