A purposefully simple design, the Mag is workhorse drop throw-off with horizontal tension adjustment and smooth, easy-adjust action. it gets it's name from a clever magnet that's integrated into the body of the throw-off. When the handle is in the up position, it won't release without a slight tug. Combined with the innovative new 3P, three-position butt plate, it might be the most reliable and versatile strainer systems we've ever built. Comes complete with gasket and all mounting hardware. Hole pattern also fits DW Delta throw-off.
