Prior to fixing, please ensure:
● Access for fitting is available
● Correct area of risk is assessed (double-risk areas may require two collars

The product must be installed correctly. Fixing lugs are already fitted to WPCS
collars. They can be fixed to solid structures with raw plugs with screws. It is
recommended that you pump a spot of Envirograf product 58 (intumescent Mastic)
into the previously drilled hole. For hollow plasterboard walls, fix with screws if there
are timber noggins to fix to, otherwise use steel toggle fixings. If WPCS are to be
fitted into an area where no noggins or blockwork to attach to, the lugs can be
re-attached to another part of the WPCS by drilling 1.5mm holes into the side of the
collar and screw into collar. WPCS’s MUST be securely fixed..
