Pemko STC4131DPK Fire-Rated Acoustic Automatic Door Bottom | Dark Bronze Finish
The Pemko STC4131DPK Acoustic Automatic Door Bottom is the industry-leading solution for high-performance sound control in architectural openings. Finished in a sophisticated Dark Bronze Anodized Aluminum, this unit is specifically engineered for environments where noise reduction is critical, such as recording studios, luxury offices, medical exam rooms, and high-end residential suites.
As part of the specialized STC Series, the STC4131DPK has been independently tested to deliver "sealed-in-place" acoustic performance. Its versatile design allows for either surface-applied or semi-mortise installation, providing a professional retrofit or a low-profile new build solution that effectively blocks sound, drafts, smoke, and light.
