12" x 3" Total-locking Scaffold Stem Caster with Mold-On Rubber Wheel

The Mold-On Rubber wheel has a rubber tread vulcanized to a heavy-duty cast iron core. Offers a shock-absorbing semi-cushioned ride with floor protection and quiet rolling operation. Rolls well over small debris, rough floors, cracks, floor joints, and other common obstacles. Economically priced cushion wheel. The black rubber tread may leave floor marks; if non-marking wheels are required we suggest a different wheel material. Works well in outdoor environments, but the cast iron core can rust if exposed to moisture; if this is a concern, consider wheels with aluminum or plastic cores.

Our 403 Scaffolding Series is built for heavy-duty scaffolding, mobile platforms, and temporary structures in demanding construction and industrial environments. Each caster includes a cross-drilled stem that bolts directly through the leg of a scaffold tube, with a total-locking pedal brake that simultaneously locks both wheel rotation and swivel motion. The 403 chassis features hardened swivel raceways with dual-row ball bearings, a formed and hardened brake shoe that locks both the swivel and wheel at the same time, and Zerk (Alemite) fittings on both the wheel and raceway for ongoing lubrication. Recommended for ergonomic scaffolding applications.

WARNING: DO NOT RIDE ROLLING TOWERS. Check that the caster is securely locked before climbing scaffolding. Do not attempt to use if the caster is faulty or has not been properly maintained.
