Hook Vs Nail

When considering your choice of slate, you should also consider the most suitable method of fixing.
Slate hooks offer a viable, perhaps even preferable choice over traditional nails in many situations.

Both fixing methods have their advantages and disadvantanges, as shown in the table below. Slatescape recommend the use of Hook fixing for our Lovat Slates (Brazilian Grey-Green) and our Cinero Slates (Brazilian Graphite-Grey).
