How It Works

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!

Comments about Zero #355, Automatic Door Bottom, Mortised for Metal Door with Double Neoprene Seal, .5" Drop:
After installing the door bottom it looks like it will work even without needing to adjust it. However, I did have to make modifications in the channel of my old door in order to get the new piece to fit correctly. This was not the "fault" of the new door bottom, but in the design of the old door.
Bottom Line Yes, I would recommend this to a friend
