Description
This fully mortised aluminium automatic drop seal features a silicone rubber gasket and internal fins.

• Dual internal sealing fins enhance acoustic and smoke containment performance.
• Supplied with high performance fire rated silicone rubber gasket and aesthetic colour matched end caps.
• Fully automatic, no power connection required.
• Simple adjustment to suit varying door gap requirements.
• Proven long term reliability.
