Individual Products — Quick Access
QWIK Slate® improves upon the traditional slate hook method by pre-applying a series of hooks on an aluminum strip. Available in various hook layout patterns to accommodate different slate widths, QWIK Slate® enables super-fast nail gun application and provides superior attachment of slate to roofing surfaces. All QWIK Slate® hooks are 12-gauge 304 stainless steel, anodized black for maximum strength and corrosion resistance. The system eliminates over-nailing and under-nailing, reduces installation time and labor cost, and makes future repairs quick and easy — a single slate can be replaced without disturbing adjacent slates.
