The GRS-FF is designed to prevent air leakage at pipework penetrations behind a radiator that is plumbed with 10mm flexible plastic barrier pipework commonly used for central heating systems in modern buildings.

- Twin plate system to maximise the benefits for first and second fix installations

- First fix mount plate anchors the pipework at the correct point of exit from the wall

- Guide channels help to curve the pipework towards the valves to prevent kinking

- Mount plate can work with various wall constructions such as blockwork or stud walls

- Second fix cover plate attached with a single screw, no plasterboard fixings required

- Multiple pilot hole locations between the two plates allows for various installation offsets

- Flexible grommets seal around the pipework while allowing for directional adjustability
