Sizing the load

Use the per-caster figure, not the set figure. Four casters at 300 lb make 1,200 lb, but a dolly on a warped floor often rides on three, so about 900 lb is a safer working load [S2].

Fit checks

  • Bolt pattern 2-3/8 x 3-5/8 in, the same as the 3 in size, so you can step up a size without drilling.
  • Overall height is 5-1/8 in, almost an inch taller than the 3 in caster. Change all four corners together.
  • Zinc-plated steel rig for indoor use [S1].

Choosing a lock layout

  • Furniture and moving dollies: all swivel, so the dolly turns in any direction.
  • Carts pushed from one end: two swivels at the handle and two rigids at the far end track straighter.
  • Carts that must stay put while loaded: pick a set with locking swivels.
