    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!

    Good door bottom seal for a flat floor

    Comments about TMH Automatic Door Bottom, Mortised, Heavy Duty, Double Neoprene Seal, .562" Drop

    Once the groove was cut into the bottom of the door the automatic door bottom installed easily. Adjustment to have the correct travel was also very easy to make. I added a metal plate where the striker hits the door jamb. This should provide a more permanent plain for it to push off of.
