410 Contender Kingpinless Casters

Both are kingpinless heavy-duty casters, but the 410 Contender is the higher-capacity series, rated up to 5,400 lbs per caster versus the 310's 4,100 lbs. Choose the 410 for the heaviest loads and the most demanding towing and shock conditions.

Kingpinless construction replaces the central bolt, which loosens or breaks under shock and towing, with a large sealed raceway that spreads the load. This gives higher capacity and far better durability under impact, which is exactly what heavy loads and towing demand.

Yes. They are built for it. Towing creates side loads and shock that overwhelm a kingpin bolt, but the kingpinless raceway has no bolt to fail and handles the impact. Rated to 5,400 lbs each, the 410 suits the heaviest tow lines and platform trucks.

Each 410 Contender caster carries 2,000 to 5,400 lbs depending on wheel size and material. Divide your total load across all casters with a safety margin, and remember that towing and shock loads spike well above the static weight, so size up accordingly.
