Four of the Original R8 Smart Casters (fully assembled).

These are awesome! I replaced the type you have to individually step on. These are better and the wheels are bigger so they roll over the expansion joints in my garage better. Would buy again! The little clips to hold it compressed during install only worked on 1 of 4 but that's no big deal if you have a clamp. And who doesn't have a clamp?

The casters are well made and high quality an excellent value for your money.

They work well. But installing at correct height took time. Loved the included extra long drill bit, and screw driver bit to get past the caster. New design has a plastic pullout u remove after installation instead of set screw (discuused on instructions). Good use cardboard template for caster positioning.
