(See also Envirograf® Product 110 for hollow wall fixing)

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.

Please Note: WPCS/C for ceiling application is only available from 2 hours protection upwards.

WPCS/C comes with hinge and pin opening.

IMPORTANT

Please note that external pipe diameters may vary between different manufacturers and systems, and ambient temperature also affects dimensions. Please select the collar size most appropriate for your application, allowing a small clearance for ease of fitting. A close fitting between the collar and the pipe surface should be the aim, but the collar should not be unduly strained in order to close it around the pipe. A fireproof sponge filler strip can be provided upon request for special applications. Please enquire with details of your application for technical advice.
