The Mark I Series metal brake answers the demand for quality and flexibility with its portable, lightweight design, heavyweight compatibility, and superior durability. Featuring the new Power Lock bar technology, Van Mark sheet metal brakes offer a cam-locking system that revolutionized the industry. The Mark I siding bender has fewer parts combined with a rugged durable design that increases productivity while also extending the overall life of the brake. Contractor model M12, along with Commercial models M12HD-M14HD, each comes with dual bending and locking handles. Contractor models are the same as the commercial model with additional C castings which will allow for the bending of some heavier metals.

The Van Mark Mark I siding brake features a wide array of bending capabilities. This aluminum brake can be used to create siding components for both residential and commercial applications including rake edge, soffit, fascia, window casing, j-channel, corner posts, window sill, and brick molds. Typical materials used for these components include vinyl, aluminum, galvanized steel, painted steel, roofing copper, zinc alloy, and stainless steel. See the chart below for bending capacities.
