FIRESTOP Trend Drop Down Seal

The FIRESTOP Trend Drop Down Seal is a highly effective, rebated door seal designed to provide a discreet barrier against fire, smoke, noise, light, and insects. Recessed into the bottom of timber doors, this seal remains hidden until activated by the closing action of the door, ensuring a seamless and clean aesthetic.

This durable seal features an aluminium body with a self-directing reinforced plunger and a high-quality, self-extinguishing co-extruded seal. It has been endurance-tested to 200,000 cycles and offers a maximum drop of 14mm. For a precise fit, the seal can be trimmed down by up to 200mm.

It is fully tested to meet rigorous safety standards, achieving up to 60 minutes of fire resistance (BS EN 1634-1 & BS476: Part 22), smoke protection (BS EN 1634-3: 2004), and acoustic reduction of up to 39dB Rw (BS EN ISO 10140-1 & BS EN ISO 10140-2).

This product is available in multiple lengths ranging from 72.6cm to 1.026m, with weights ranging from 380g to 540g. Please select your required length and specification from the options below.
