How it Works: Automatic Door Bottoms utilize a concealed flat spring mechanism and plunger. When the door is closed, a brass plunger is compressed to automatically lower the seal, starting from the hinge side first. This motion ensures a smooth usage even on an uneven surface and prevents drag. The seal is automatically raised upon opening. These automatic door bottoms have been successfully tested through 5 million cycles!
