The Thermalweight dock door is the first knockout door specially developed for cold storage. It is made of four-inch thick panels, with the knockout concept reducing door maintenance, repair costs and dock downtime. When the door is hit, the panel releases from its guides rather than resisting and breaking. Repair consists of a quick yank on the panel to reset it back into the door guides. Door gaskets are panel-mounted, enabling the door to protect its own seal, and most of the door parts are plastic for easy cleaning to meet sanitation requirements.
