What's New

Planet SN

Planet's Sliding Door Solution

The Planet SN is the world's first, and only, ‘buttonless’ drop-seal for sliding doors. Actuated by a trigger plate mounted to the floor, the Planet SN provides 48 dB attenuation on both exposed and sliding doors. ADA-compliant, the Planet SN operates smoothly and quietly with zero force, meaning the door can stay closed without having to be locked or latched.
