Frequently Asked Questions

What is the load capacity of this caster?+

This 4" x 1.25" HI-TECH Caster – 275 lb is rated to 275 lbs per caster. Size a set by dividing the total load by the number of casters, and for uneven floors assume 3 of 4 casters carry the load. Keep continuous-use loads within about 75-80% of the rating.

What plate size and bolt pattern does it use?+

This caster uses a top-plate mount. Measure your existing mounting holes before ordering; if you are replacing casters, match the bolt pattern - most standard patterns interchange across brands.

What temperature range can this caster handle?+

Rated for -20°F to 180°F. Operating outside the rated range can reduce wheel life and load capacity, so match it to your environment (wash-down, freezer, oven-adjacent, etc.).

What is the overall mounted height?+

The overall height (floor to top of plate or stem) is 5.25". Account for it when checking equipment clearance, dock height, and ergonomic working height.

How do I order, and what are the terms?+

We accept purchase orders and offer Net 30 on approved accounts, ACH, and all major cards, plus tax-exempt ordering with a resale or exemption certificate. Volume discounts apply automatically; request a bulk quote for large or recurring orders. Stock items carry a 30-day return policy in unused condition (made-to-order items are non-returnable once production starts).
