- Can the automatic door bottoms be used on sliding glass door systems?
No. The automatic door bottoms are designed for use on the push side of hinged doors.
Product Description
Our Automatic Door Bottom utilizes a flat spring mechanism, which activates when closing the door, lowering a neoprene seal insert against the floor or threshold to create a sound seal. These are for use on the push side of the door. The frame compresses a protruding hinge-side “plunger” as the door closes, to activate the spring. The Automatic Door Bottom then drops a seal in a scissor-like motion from the hinge side, adjusting to the floor from a pivoting point. As the neoprene seal compresses, it forms a tight, secure seal against the saddle or floor. The sweep retracts automatically as the door opens.
Our Automatic Door Bottoms can be made to fit any sized door up to 48″. We offer a surface mounted unit, as well as a mortised and semi-mortised version. Surface mounted bottoms install without removing the door from its hinges. Semi-mortised bottoms may require door removal if the door does not have a cut out. Mortised bottoms will require removal of the door prior to installation. These door bottoms are available with a clear anodized aluminum or dark bronze anodized aluminum finish.
Automatic door bottoms are often used in conjunction with door jamb seals and acoustic thresholds or as an Acoustic Door Seal Kit.

Customer Reviews
A little work required but the door shuts with a snug fit and the sound buffer is even better than I hoped.
Works so great it definitely blocks all sounds like it should
It works really well.
My only gripe is the lack of instructions. Installation was quite the guessing game. How far should the poison be from the door jamb? How do you estimate the amount of drop before screwing is into the door? What’s the order of installation / arrangement of all the pieces? How does this piece suit against the threshold? The provided instructions left a lot unanswered.
Cuts instrument sound bleed with amazing results.
Easy to fit and mount, looks great when installed.
Very good product
Best solution for sound leaks at doorways.
GOOD PRODUCT BUT EXPENSIVE
THANK YOU
