This is the toolless thumb screw that holds the splash guard in place on a Polar Cool Zone 11K evaporative cooler. If yours is stripped, missing, or won't grip anymore, this replacement gets you back into the spray bar and pads without hunting for a screwdriver.
This thumb screw is a maintenance-access part, not a structural fastener, but it still needs to hold its grip through repeated hand-tightening cycles and outdoor exposure near the spray bar. Polar Cool built it from durable material intended to withstand regular use and environmental conditions. 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.
