Schall-Ex™ L-15 FS

the retrofit drop seal solution

athmer’s Schall-Ex™ L-15 FS is a retrofit solution for acoustic isolation. While the other Schall-Ex™ models require you to prep the door for the seal prior to hanging it, the FS series allows you to get the benefits of a great drop seal on any door even after it’s hung. The FS series provides a clean solution with concealed fasteners, and optional finishes to help it blend in.
