E-line Rigid 4"x2" Rubber Donut USA-Made TPR Wheel 4"x4.5" Plate Caster With Tread Lock Brake; Part# ER4X2TPDBTBK

About This Caster - ER4X2TPDBTBK

Set this 4-inch rigid on the back corners of a hand-pushed quiet-area cart that rolls light and then has to hold, where a ball bearing eases the push and the brake locks the corner.

The wheel is Pemco's Thermo-Rubber donut tread on a polypropylene core: a soft grey thermoplastic rubber that rolls quiet, leaves no marks, and cushions floor seams. The precision ball bearing cuts the push effort so a loaded cart moves by hand, the tread-lock brake presses on the wheel to hold the cart still, and the rigid fork holds the line on a low 4-inch deck. The tread holds to 180°F.

Ideal applications

• Back corners of hand-pushed quiet-area carts, braked
• Ball bearing for a light push, tread lock to hold
• Cushioned donut tread silent and braked on a finished floor

Skip the brake if the corner only rolls; the plain ER4X2TPDB is the no-brake version.

Pairs with: plain ER4X2TPDB rigids on the corners that only roll.

Wrong fit? No brake needed or a roller bearing? See the plain ER4X2TPDB and the roller tread-lock ER4X2TPDTBK.
