E-line Rigid 4"x2" Polyurethane (TPU) USA-Made Wheel 4"x4.5" Plate Caster With Tread Lock Brake; Part# ER4X2TUMBTBK

About This Caster - ER4X2TUMBTBK

Set this 4-inch E-line rigid on the braked back corner of a low towed cart that parks on a grade, the TPU polyurethane caster whose firm maroon tread carries the load while a precision ball bearing rolls cool and a tread lock holds the rear against roll-back.

A TPR rubber wheel flat-spots under a heavy load; the Pemco TUM polyurethane tread on a polypropylene core carries the higher E-line load without setting and stays non-marking, the precision ball bearing runs cool and true, and the tread lock clamps the rear wheel so a parked cart cannot roll back off a slope. The 4-inch diameter keeps the rear low, and the 4 by 4-1/2 top plate bolts to a flat deck. USA-made for fast shipping.

Ideal applications

• Braked back corners of low towed carts on a grade
• Rear wheels that hold against roll-back, non-marking
• Cool precision roll under a braked low rear

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

Pairs with: the plain ER4X2TUMB precision rigid on the rolling corners.
