Load capacity ratings of the Gate Casters & wheels are NOT related to the springs. Load capacity ratings are offered as an idea of what the gate casters will carry without failure. They are NOT absolute, but rather depend on the usage and service.

One side of a gate is usually attached to a column which supports most of the weight of the gate. The purpose of the spring in a gate caster is only to keep the caster wheel touching the floor when the floor is not level. If the floor level from the lowest point to the highest point is more that 1″ then the gate caster will not be able to touch the floor at one end, either at the lowest point or at the highest point.

For the suspension to function, the gate’s weight must be heavy enough to compress the spring into its active working range. If the load is too light, the spring remains fully extended (‘topped out’) and the caster acts as a rigid mount, offering no dampening.

Mount the ( Spring Loaded ) Caster at the lowest point so that the spring compresses as the caster moves up to the high point.

1″ deflection: There can NOT be more than 1″ difference between the lowest and the highest points on the floor surface.
