The Faithfull Upright Clamp is designed to be a helping hand when working alone, securely holding doors, sheet materials, studs for interior wood framing, and many other applications where material support is needed. It allows users to easily mark-out, route-out, plane, and drill without the difficulty of holding the material in place with one hand. The clamp's strong grip secures materials up to a width of 55mm, making it suitable for working on FD30 and FD60 fire doors. It can be operated by hand or foot, depending on the application. The sturdy base is usable on tabletops and floors and includes support screw holes for added stability with heavy objects or when secured to an additional base (not supplied). Specifications include a capacity of 15-55mm and a 5-year guarantee.
