E-line Swivel 4"x2" Polyurethane (TPU) USA-Made Wheel 4"x4.5" Plate Caster With Total Lock; Part# ET4X2TUMD

About This Caster - ET4X2TUMD

Choose this 4-inch E-line swivel for a low non-marking wash cart that must park dead square on a wet floor, the TPU polyurethane caster whose firm maroon tread bears the load while a greaseless Delrin bore steers the damp and a total lock freezes the wheel and the swivel.

A rubber wheel sets flat under load and a packed bore seizes in a wash area; the Pemco TUM polyurethane tread on a polypropylene core resists flat-spotting under the E-line load and stays non-marking, the Delrin bearing needs no grease and cannot corrode, and the total lock pins the wheel and the swivel head so a wash cart holds square on a wet slope. The 4-inch diameter keeps the deck low, and the 4 by 4-1/2 top plate bolts to a flat deck. USA-made for fast shipping.

Ideal applications

• Low wash carts that park dead square on a wet floor
• Greaseless fronts held square against drift
• Damp aisles where the cart cannot rotate out of line

Skip the polyurethane wheel if the cart runs near heat over 180°F or on oily floors; a phenolic E-line wheel shrugs off oil and heat to 250°F where TUM softens.

Pairs with: a matching 4-inch E-line rigid on the back corners for a square-parking wash cart.
