These Automatic Door Bottoms ensure an efficient seal with an adjustable plunger that is compressed against the frame as the door is closed, activating a concealed flat spring mechanism. This mechanism drops the seal smoothly from the housing in a scissor-like motion. The seal compresses on either even or uneven surfaces and retracts automatically when the door is opened.

It is fitted with a two Vinyl bulbs to ensure a quality seal. Seal drops up to 0.5" and is fire rated. Product is non-handed and custom cut to size.
Maximum order length is 60" unless noted otherwise. Lengths up to 96" on some models available as engineering special order.
