Genius Roof - Hallhooks for Fitting Slates (10 Pack)

The Hallhook from Genius Roof Solutions is a hidden, permanent slate fixing used when replacing a broken slate, including after a solar panel bracket has been mounted through a slate roof. Each pack contains 10 Hallhooks and 1 Hookpull tool. The Hallhook sits between two slates with its lower hook resting just above the finished slate baseline; a nail fixing gives a vertical line that resists lateral movement, and an upward-biased spring keeps contact with the underside of the slate above while staying hidden from view. Two nail-fixing positions on the hook suit head laps of 75 mm and 100 mm. Once the replacement slate is slid into place, the hookpull draws the Hallhook's spring up to catch the slate's underside, then is removed, leaving no visible fixing. It is also used for general slate repair, roof-light and window installations, slate vents, and conservation or heritage roofing work.
