Fabrication and welding shop casters in polyurethane, semi-steel and steel, 2-3/8 to 12 in wheels, rated 900 to 4,000 lb per caster.
Which fabrication / welding-shop path are you on?
Mount type and floor duty drive the right assortment. Pick weld-on pad, bolt-on plate, V-groove track, kingpinless shock-load, or floor lock, then confirm capacity and dimensions on the product page.
Weld-on caster pads and shims for fab tables, carts, and fixtures where you want a permanent plate dock. Match pad size to your caster top plate before welding.
Bolt-on plate mounts for welding-shop carts and fixtures. Start in this fabrication hub, or browse the broader plate-caster catalog when you need more sizes.
V-groove wheels and track casters for carts that must stay on a fixed path. Confirm groove and track size on the product page.
Kingpinless raceways for shock and side-load duty common on shop floors. Confirm capacity and plate size on the product page.
Floor truck locks and hardware to secure carts during weld, fab, or assembly. Pair with the casters above, locks are not a substitute for load rating.
Also useful on fab floors: Metal / steel wheels · Heavy-duty casters · Heavy-duty hub
