YDB305

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.

YDB305 automatic door bottom creates a tight seal at the bottom of doors to prevent infiltration of sound, light, drafts and more. Equipped with a high quality, long-lasting vinyl seal and mechanism that has been successfully tested through 5 million cycles! This model is fire rated. Available in choice of anodized finishes and 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.
