Product Description:

5″ x 2″ Ground Glider Wide Caster w/brake (Upgrade for R8, R10)

The R5x2CSTR is an upgrade caster for the R8RT and R10RT.

Replacement caster for models R6G & R11G.

Caster stem is 1.5″ x .5″ with 13 threads per inch. 

All casters are sold individually, but you must purchase (2) for use as an upgrade to the R8RT or R10RT.
