This is a replacement caster kit for Polar Cool 18" evaporative cooling fans — four solid rubber wheels (two swivel, two rigid) that let you reposition a cooler without wrestling with a cracked or flat-spotted wheelbase.
Solid rubber casters don't go flat, which matters on a part that often gets forgotten until a wheel splits mid-move. This kit is built specifically for the Polar Cool 18" evaporative cooling line, replacing worn or cracked factory casters with a matched set sized for that chassis. Note: If you would like to review the manufacturer Product Specifications, Warranty, Brochure, etc., for this system, please refer to the "Resources (System Manuals and Warranty)" Tab above on this page.
