Rp8Si Automatic Drop Threshold Seal

RP8Si Automatic Door Bottom Seal

The RP8Si is a high-performance automatic door bottom seal designed to provide effective acoustic, smoke, and weather sealing for commercial door systems. Suitable for timber, steel, and aluminium doors, it automatically lowers a sealing gasket against the floor when the door closes, helping to reduce sound transmission, restrict the passage of smoke, and improve environmental control.

Its concealed design ensures a neat, professional appearance while delivering reliable sealing performance in demanding commercial environments. Engineered for durability and smooth operation, the RP8Si is ideal for healthcare, education, commercial, and public buildings where acoustic performance, smoke containment, and energy efficiency are important.

The RP8Si is suitable for both new installations and retrofit applications and is approved for use on K2 fire door systems.
