Pemko STC411 Full Mortise Acoustic Automatic Door Bottom

The Premier Pemko Acoustic Automatic Door Bottom

The Pemko STC411™ automatic door bottom is the latest design for high-quality performance in acoustic control and sound attenuation. The newly designed spring assembly increases the pressure applied on the drop bar across the entire length of the automatic door bottom, maximizing seal performance.

When installed, the high quality, multi-finned seal of the Pemko STC- series automatic door bottoms conform to slight irregularities in thresholds, sills, and most flooring materials. The seal not only provides superior acoustic performance but also seals the opening against wind and debris to improve its overall energy efficiency.
