The original Mark I Series™ was introduced in 1983 and has established Van Mark as one of the most innovative companies for the siding and roofing industry. The launch of the Mark I Series™ introduced the Cam-Locking system and offered contractors a durable and virtually maintenance-free material locking method.
POWERlock™ provides a strong clamping without need for adjusting when changing material.
Traditional hinge system to “auto-measure” 3 ⁄ 4″ hem, great for fitting over standard “One by” lumber and siding.
Increased bending radius simplifies hemming & over-bending resulting in faster, easier operations.
