At Tech Team we provide 3 different gate wheel / caster options. It is best to take stock of your particular gate problem to get the correct one and have a successful outcome. Our 716 and 884 industrial gate casters are intended to give the best result when attached to the inner or outer face of the gate and have a compression spring to provide support on uneven surfaces. Our 767 gate wheel is designed to supply support to the end of a tubular steel agricultural gate along the radius of its travel.
