FireSealsDirect Universal Low Profile Threshold Plate - 40mm x 4mm x 1m

The FireSealsDirect 40mm Threshold Plate is an ultra-low profile floor plate designed to provide a reliable sealing surface for automatic drop-down seals on hinged and double-swing doors. Engineered for environments where accessibility is critical, such as hospitals, schools, and public buildings, it ensures full compliance with escape route regulations while maximising the acoustic and smoke containment performance of the door set.

The primary challenge when sealing doors over tile, carpet, or uneven transitions is achieving a continuous seal without creating a trip hazard. This unit solves that problem with a height of just 4mm. This ultra-slim profile is virtually unobtrusive to foot traffic and wheeled equipment, yet it provides a dedicated, level platform for the drop-down seal. This ensures the gasket compresses fully across the entire width of the door, preventing sound leakage and drafts that commonly occur when seals deploy directly onto textured flooring.

Durability is key for floor-mounted hardware. Manufactured from 6060 T6 aluminium alloy with a silver anodised finish, this plate resists wear and deformation even in high-traffic zones. The unit allows for versatile installation; it can be bonded to the floor using construction adhesive or screw-fixed (requires drilling and countersinking on-site) depending on the substrate. This flexibility makes it an essential component for contractors needing to upgrade door performance without extensive floor remediation.
