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.
YDB310 Fully Mortised, Heavy Duty, Sound Rated Automatic Door Bottom provides the best sound seal possible for normal sound levels, and will prevent infiltration of lights, drafts and more. Fitted with a sponge neoprene drop seal and high quality mechanism that has been successfully tested through 5 million cycles! Rated for fire, smoke and sound infiltration. Length is custom cut to size.
Maximum order length is 60" unless noted otherwise. Lengths up to 96" on some models available as engineering special order.
