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 #320, Automatic Door Bottom, Mortised Regular Duty with Neoprene Seal:
It works as described. You should know that as soon as the switch makes contact with the door jamb, the sweep will start dropping. As it does this, it may start touching any rug you have near the door. In my case (32" door) it starts to drop when the handle-edge of the door is about 6" from the jamb. I pulled the rug about 2" away from the threshold and this seems to help. It's nice that it can be adjusted so you get a good seal. I plan to add this to other doors in the house. We have an inside door from our laundry room that connects to the kitchen. It will be nice to have a sound-seal to prevent the machine noise from bothering us in the rest of the house.
Bottom Line Yes, I would recommend this to a friend
