4" Polypropylene Rigid Caster - 120RW04201R

About This Caster - 120RW04201R

Set this 4-inch polypropylene rigid on a fixed corner of a steam-clean or high-heat washdown cart where other treads would soften.

The white polypropylene wheel takes heat to 290°F, the highest in the 120 line, and shrugs off the harshest chemicals and moisture, which makes it the pick for steam-clean and autoclave-staging carts. It is economical and lighter-capacity than nylon, and as a hard wheel it gives no cushioning, so it suits sealed concrete. It rolls on a corrosion-resistant stainless steel roller bearing inside the kingpinless stainless frame, and as a rigid caster it tracks straight on the fixed corners. It bolts on a 4 by 4-1/2-inch top plate at a 5-5/8-inch mount height and holds from -20 to 290°F.

Ideal applications

• 4-inch white poly rigid on a steam-clean cart fixed corner
• 290°F tread tracking straight on a stainless roller bearing
