The FIRESTOP Trend Drop Down Seals are designed to form an effective barrier against the outside climate, including noise, light, fire, smoke and insects, and are activated by the closing action of the door, meaning the seal only drops down when the door is closed. The seals are available in a variety of lengths and can be cut down to size (200mm maximum trimming length). These units are recessed into the bottom of the door for a discrete installation.

It has an aluminium body with a self-directing reinforced plunger and is endurance-tested to 200,000 cycles with a 14mm maximum drop.
