Intumescent pipe collars installation options

The pipe collars are designed for surface mounting, with the option to fully or semi-cast into masonry floors or walls.

The fixing brackets provided can be used for securing the sleeve with non-combustible screws or bolts, or to assist 'keying-in' if collars are for recessed installations.

For horizontal installations the collar may be surface mounted or recessed but should be located on one
or both sides according to the direction of risk.
