PLANET KT Threshold Sealing Strip LI-PL-011 960mm Cuttable Silicone Gasket 48dB

Product Overview

The PLANET KT threshold sealing strip with drop-down silicone gasket is installed at the base of doors to provide smoke and sound protection in commercial and residential buildings. With a standard length of 960 mm, it is suitable for use in interior doorways and environments that require enhanced acoustic or smoke control, including offices, hotels, and healthcare facilities. The strip achieves sound insulation up to 48 dB and features a 16 mm extension for effective sealing.
