Patented Installation System
QWIK Slate®
QWIK Slate® replaces traditional nailing with a precision hook system — cutting installation time in half while making future repairs as simple as lifting and replacing a single slate.
QWIK Slate® strips use hooks to support the slates rather than nailing, allowing fast installation and easy maintenance. Hook strips are applied with a standard nail gun, dramatically increasing productivity and eliminating the risk of over- or under-nailing.
Available Colors
Lightweight Slate System
Slate Shield
Genuine slate. Half the weight. Unmatched performance.
Slate Shield combines traditional hook fixing with an advanced HDPE backing panel — reducing installation weight by half while maintaining the authentic appearance and century-long lifespan of natural Vermont slate. The patented Butterfly hook delivers wind resistance no synthetic can match.
