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!

Installation Guide

Click here for a Printable Copy of How to Install a Mortised Automatic Door Bottom.

Automatic Door Bottoms are available with three mounting options: Surface Mounted, Semi-Mortised and Fully Mortised. A surface mounted application can be applied without removing the door from its hinges. For a semi-mortised, if the rabbet in the door is cut-out already, the door does not need to be removed. For a fully mortised application the door should be removed before starting.

Comments about Zero #369, Automatic Door Bottom, Mortised, Heavy Duty, Double Neoprene Seal, .562" Drop:
Hired a carpenter to install a number of these in my home for soundproofing. It is not a simple matter to cut the channel in the bottom of the door to accommodate the fully mortised product. This product requires a 1 3/4 inch thick door. Very heavy duty; works well.
Bottom Line Yes, I would recommend this to a friend

  • I Used On Wood Front Door
Comments about Zero #369, Automatic Door Bottom, Mortised, Heavy Duty, Double Neoprene Seal, .562" Drop:
I used this on a wooden front door that had an uneven natural stone doorstep. I needed something to seal out the wind & rain and this product worked - the seal is excellent. The previous seal I used was not an automatic bottom, and would scrape across my hardwood floor on the inside, sounding painful and scratching the floorboards. This no longer happens. As long as the rubber seal doesn't deteriorate too quickly I will be very pleased with this product.
Bottom Line Yes, I would recommend this to a friend

Comments about Zero #369, Automatic Door Bottom, Mortised, Heavy Duty, Double Neoprene Seal, .562" Drop:
It was easy to install and works well to add 3/4 inch to the door to seal it, but lifts when the door is opened so it opens smoothly but keeps drafts out.
Bottom Line Yes, I would recommend this to a friend
