Planet US drop seal

Mortised

A slimline, mortised automatic drop seal designed for timber, metal, and PVC doors. Its ultra-narrow 8mm profile makes it ideal for minimalistic applications and allows installation alongside the Planet KR flush bolt. Featuring a high-efficiency mechanism with hinge-side triggering, it enables parallel lowering and automatic compensation for sloping floors. Suitable for fire and smoke-shielding doors, with a seal height of up to 20mm.  Alternatively, an optional bevel lip is available for uneven floors, accommodating gaps of up to 24mm.
