The Hallhook™ is a permanent, secret and fail safe device that should be used when replacing a broken slate.
Product inventor Jimmy Hall, a slater and tiler for the past 40 years, had tried all the slate repairs on the market. Some of the problems he encountered were:
- Plastic products are visible, unsightly and time consuming to install.
- Some metal fixings are flimsy. Others take too much time, are awkward to prepare, and if wrongly prepared the head of the slate could slip off the upper batten.
- Fixing with a slate hook involves trimming the head of the slate, thereby losing some head lap (a building inspector may not accept this).
