Acoustic Drop Seals - (Rebated)

The Acoustic Drop Seal Type37R is a rebated automatic door bottom seal which is spring loaded to lift clear of the floor as soon as the door leaf is opened by a few millimetres. Complies with Approved Documents E and M for acoustic rating and DDA access requirements. The seal forms an effective barrier against the outside climate, noise, light, insects etc.

Acoustically tested on proprietary fire doors, suitable for new and retrofit in all types of wooden doors. Designed for rebated applications, mounted into a 13mm x 28mm groove that has been morticed into the bottom edge of the door, it is operated automatically by pressure against the door jamb on its adjusting screw and seals when the door closes and retracts automatically when the door is opened.
