Welding tips

  • Use the unplated pads for welding. Zinc plating gives off harmful fumes when heated, so grind it off first if you must weld a plated part.
  • Tack the pad, check it is flat and square, then weld it out.
  • Bolt the caster on after the pad cools.

Quick change pads

A quick change pad lets a caster be swapped without cutting or rewelding. It suits fleets of carts where casters wear out often.
