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 headlap (a building inspector may not accept this).
