What are total locking casters and how do they work?

Total locking casters (also called total lock or dual lock casters) feature a brake mechanism that locks both the wheel rotation and the swivel movement simultaneously, providing complete immobilization. CasterHQ offers total locking casters in light-duty plate mount, threaded stem mount, and heavy-duty plate mount configurations for applications requiring maximum stability and safety.

What are kingpinless casters and when should I use them?

Kingpinless casters (also called heavy-duty casters) eliminate the traditional kingpin design, distributing load across a larger raceway for superior weight capacity and durability. Use kingpinless casters for extreme loads (typically 1,200+ lbs per caster), high-impact applications, or when maximum longevity is required. CasterHQ offers kingpinless casters in various wheel materials and sizes for industrial manufacturing, warehousing, and material handling.
