The Dial 4797 is a metal pad frame latch designed as a direct replacement for Arctic Circle evaporative coolers that use metal latch hardware. Evaporative coolers, also called swamp coolers, rely on water-saturated pads to cool incoming air. The pad frame holds these cooling pads in place against the cooler cabinet. When the latch that secures the pad frame wears out, breaks, or goes missing, the frame can shift or come loose. A loose pad frame allows warm, unconditioned air to bypass the pads, reducing cooling efficiency and increasing energy use. Replacing a damaged latch restores a proper seal and keeps the cooler running at full capacity. The Dial 4797 is made from metal and finished in silver, giving it the strength to hold up against repeated use, outdoor conditions, and the moisture-heavy environment inside an evaporative cooler cabinet. Each latch ships complete with a mounting screw, so installers have everything needed to complete the repair in one package. No hunting for a separate hardware screw. HVAC technicians, evaporative cooler service professionals, and do-it-yourself homeowners will find this a straightforward swap. The latch fits Arctic Circle cooler models that use metal pad frame latches, making it a targeted replacement part rather than a universal fit. Always verify compatibility with your specific cooler model before ordering. Dial is a well-established manufacturer of evaporative cooler components, including pads, motors, pumps, floats, and hardware. Their parts are widely used in residential and commercial evaporative cooling systems across dry climates where swamp coolers are the primary means of cooling.
The Dial 4797 restores a secure pad frame connection on Arctic Circle evaporative coolers, helping maintain proper airflow and cooling efficiency. It includes a mounting screw and installs quickly with minimal tools.
