Adjustable Cover Plate
Lightweight plate with centre hole but in two halves.
Material:
galvanised steel
Applications
- Where a vent passes through a sloping roof or ceiling this adjustable firestop accommodates the oval shape. A firestop spacer must be used on both sides of the penetration to provide a barrier to fire and maintain a 50mm air gap clearance to combustible materials.
- If using a support plate where the pipe penetrates then only one firestop plate on the underside is required.
Installation
The plate can be screwed down on the underside of the ceiling or the loft side of a pitched roof.
Approvals
HETAS, BS4543, OFTEC, 4 hour fire rating to BS476 (part20).
