Intumescent Kit, Fire Protection

Product Details

Intumescent Kit, Fire Protection (Part No: 911.81.058) is designed to help your door hardware meet the demands of passive fire protection. Built for seamless integration with lever action flush bolts, this intumescent kit supports fire resistance performance up to 30 minutes (FD30)—ideal for commercial, public-facing, and specification-led projects where compliance and confidence matter.

When exposed to high temperatures, intumescent materials expand to help slow the spread of heat and protect the integrity of the door assembly. That means you can enhance your architectural ironmongery specification without compromising the clean, flush appearance typical of modern flush bolt hardware.

Material & build: Manufactured from 1 mm thick material, the kit is sized to provide reliable coverage and a professional finish. The physical dimensions are:

Length: 235.00 mm
Width: 70.00 mm

As part of your Architectural Ironmongery range—within the Door Hinges and Intumescent Kit category—this FD30 flushbolt accessory is a practical choice for contractors, installers, and architects sourcing compatible fire-rated components.

If you’re upgrading or specifying lever action flush bolts for a fire-rated door, choose Intumescent Kit, Fire Protection to complete the system properly. Add it to your basket to help ensure your door hardware package is ready for the next stage of installation and certification.
