Semi Pneumatic Casters

Hamilton Cush-N-Tuf Casters Series 4000

Hamilton

Cush-N-Tuf™ Casters Series 4000 - Cap. to 850 lbs.

Cushion rubber tires on high-impact polypropylene wheel centers suit Cush-N-Tuf™ Casters for fragile loads, or for service outdoors, over rough floors, dockboard lips and elevator sills. Unlike pneumatics, Ace-Tuf® tires won't deflate and can't be punctured.

  • Swivel Construction – cold forged steel mounting plate and horn base with formed steel legs continuously welded to horn base.
  • All Cush-N-Tuf Rigid models feature rugged plate steel construction, with legs continuously welded inside and outside to mounting plates that match the bolt patterns of the swivels.
