Product Overview

The PLANET FT drop-down threshold sealing strip is designed to provide automatic bottom door sealing for enhanced smoke and acoustic protection. With a 1150 mm length and silicone gasket, it is commonly used in commercial and institutional buildings where noise reduction and smoke control are necessary, such as hotels, offices, and healthcare facilities.
