Planet MF-plus, FH+RD (fire-retardant+smoke-shielding)
Description
The Planet MF-plus FH+RD is an automatic drop-down door seal designed for fire-rated and smoke-resistant doors made of wood, metal, or PVC. Its parallel drop mechanism automatically lowers when the door closes to seal the gap between the door leaf and the floor, without dragging or damaging the surface. Providing up to 16 mm sealing height and acoustic performance of up to 54 dB, it helps improve building safety, comfort, and energy efficiency. With silent one-sided activation, automatic compensation for uneven floors, and a compact aluminum profile, it is a reliable solution for demanding commercial, institutional, and architectural applications.
