Door drop-down seal Planet US, silicone

The Planet US door drop seal is a high-quality, easy-to-fit drop seal for internal doors made of wood, metal or plastic. It is screwed directly to the bottom edge of the door leaf and, thanks to its parallel drop, one-sided release and durable silicone lip, provides reliable sealing against draughts, dust and noise. The robust aluminium construction and simple stroke adjustment make the Planet US the ideal solution for renovation, retrofitting and new build – especially where quick installation and high operational reliability are required.

Further information 

The Planet US is a classic screw-on drop seal that can be mounted quickly and easily. It provides a reliable solution, particularly in older buildings, where floor conditions are uneven or where retrofitted sealing is required. The silicone lip is elastic and temperature-resistant, so it provides a lasting seal without deforming. Thanks to the one-sided release, the seal lowers evenly and effectively closes the floor gap – ideal for residential and commercial areas.
