2-76 Series Casters

KINGPINLESS DUAL WHEEL CASTERS

RWM’s 2-76 Series Kingpinless™ Dual Wheel Casters feature all of the benefits of our patented Kingpinless™ raceway and offer twice the capacity load.  Dual wheel casters offer high weight capacities with minimal overall heights, better load distribution, floor protection and mobility than single wheel casters. This is a result of spreading the weight over a wider floor area while offering wheel differential action, resulting in less friction between the wheels and the floor, requiring less effort for the caster to swivel. Our 2-76 Series Casters are proudly made in the USA!

FEATURES

To order a rigid caster, change the “S” to “R” in the model number. For example: “2-76-CIR-0630-R”. To order rig only, omit the blue letters. For example: “2-76-0630-S”. Dimensions shown are nominal. If precise dimensions are required, consult your RWM representative. For approximate weight of our rigid casters, deduct 5.4 pounds per item.
