4" YELLOWISH NYLON TOPBRAKE

This 4″ white-wheel total-brake caster offers complete equipment immobilization by locking both the wheel rotation and swivel raceway simultaneously. Its sturdy wheel composition provides high impact resistance and low rolling effort across smooth indoor facility floors.

Ideal for mobile work benches, staging dollies, and utility racks, it prevents unwanted swivel drift and wheel roll during stationary operations. The dual-lock mechanism is easily engaged and released via a single foot pedal.
