Revvo Caster Co. Inc. introduces its new SingleTech Combi total lock swivel casters. Available in 12 single-wheel models, the new Revvo caster range is designed for medical equipment, hospital beds and stretchers, appliances, furniture and retail displays, the company says. They are available with a fully-enclosed, positive mechanical brake and locking system for when all casters in a combination set need to be locked simultaneously.

The locking system uses complementary metal teeth on the wheel hub and swivel pin and does not cause the wear on brake pads and tire surfaces common to conventional friction brakes, the company states. Available in four total lock and eight total lock models with load capacities from 198 to 300 lbs and a variety of options also available such as color finishes and electrically conductive tires.
