5"X2" Stainless Steel Top Plate Caster with Rubber (Flat/Grey) Wheel - D4.05108.451 SS

About This Caster - D4.05108.451 SS

Put this 5-inch Defender D4 rigid under a quiet, finished-floor cart that runs in a wash-down area and wants a stable, planted footprint.

The wheel is grey flat-tread Performa rubber, Colson's non-marking institutional tread that runs quietly and protects finished floors, with a flat profile that puts more rubber down for steady rolling. At 5 inches it clears thresholds more easily than a 4-inch wheel while keeping the deck low. The Delrin plain bearing runs grease-free and corrosion-proof, ideal for sprayed-down rooms, and the stainless steel frame stands up to corrosion. Soft rubber keeps the load class modest, so this is the quiet, low-upkeep choice rather than a heavy hauler. Rigid means it tracks straight at the rear. It serves from -45 to 180°F.

Ideal applications

• Quiet 5-inch wash-down carts on finished clinical or food floors
• Maintenance-free stainless rigs that must stay non-marking
• Straight-tracking rear corners wanting a stable flat-tread footprint

Keep the load within the soft-rubber class, confirm the flat tread suits the cart, and check the 6-1/2-inch mount height before ordering.

Pairs with: a matching Defender D4 swivel up front so the cart steers while this rigid tracks straight, from the Colson collection.
