Free shipping in the continental USA (Alaska and Hawaii not included).
Stainless Black Anodized 3" Headlap: 0.1200 gauge, by the 25-pound box (about 81 hooks/lb or about 2,000/box). Blunt points for safety. For slates with 3 inches or less of headlap.
Stainless Black Anodized 4" Headlap: 0.1200 gauge, by the 25-pound box (about 75 hooks/lb or about 1,875/box). Blunt points for safety. For slates with 4 inches or less of headlap. When you need a stronger, tougher slate hook, go with stainless steel. Stainless slate hooks are stronger than copper and are recommended whenever the roof decking is hard, as on old oak roof boards, or even old yellow pine, both of which tend to bend copper slate hooks. These black anodized slate hooks are not shiny and are relatively invisible.
Copper Large 3" Headlap: 0.1250 gauge. For up to 3-inch headlap. About 44 hooks per pound or roughly 1,100 hooks per 25-pound box.
Copper Large 4" Headlap: For up to 4-inch headlap. About 40 hooks per pound or roughly 1,000 hooks per 25-pound box.
Galvanized: For standard thickness slates, and up to 3 inches of headlap. Approximately 80 per pound (2,000 per box). These electro-galvanized slate hooks will eventually rust, but if the roof is old and has less than 25 or so years of life remaining, then galvanized slate hooks are a good choice (think barns, or PA black slate roofs). When you need a stronger, tougher, but less expensive slate hook, go with galvanized steel. Blunt points for safety. Great for repairing asbestos shingle roofs too.
Slate hooks are used to install replacement slates during repairs, and for replacing slates left out during the installation of a new slate roof where the scaffolding (roof jacks) are temporarily nailed onto the roof. Some slaters use nothing but slate hooks for repair work. They are easier than the nail and bib when working with new or especially hard slates. It's always a good idea to have some of these hooks on hand. Can be used on most asbestos roofs too.
