PLANET KT Drop Seal Threshold Bar LI-PL-012 1085mm Acoustic 48dB Smoke Control

Product Overview

The PLANET KT Drop Seal Threshold Bar, at 1085 mm length, is engineered for integration at the bottom edge of doors in commercial and institutional buildings. Fitted with a silicone automatic drop seal, it provides both smoke and acoustic sealing to meet demanding performance needs in high-traffic or multi-unit environments. Its drop action offers a maximum seal projection of 16 mm, supporting effective barrier functions even for uneven floor surfaces.

The key advantage of this model is its impressive sound insulation value, rated up to 48 dB, which is significantly higher than standard drop seals. This feature is crucial for office, hotel, or healthcare buyers who need to guarantee certified noise isolation between rooms or corridors. The ability to trim the bar by up to 100 mm further increases installation flexibility, making it ideal for fit-out contractors or bulk procurement in projects with various door widths.
