LAS1212K Batwing®-On-A-Stick Perimeter Seal
Kerf fit
The LAS1212K Batwing®-on-a-stick is a smoke and acoustic seal designed for easy installation with its innovative kerf fixing feature. The 12mm profile, with a double fin design provides a reliable barrier against smoke and sound while minimising resistance when opening and closing the door.
Made from a flexible elastomeric material, the LAS1212K boasts long-lasting performance as the fins spring back to their original shape after each use. Suitable for both single and double leaf doors on the head and jambs, this Batwing® seal installs with minimal disruption, offering a simple solution for smoke and acoustic containment.
