The Hornady Quick Detach Universal Mounting Plate Assembly allows the user to easily attach and detach Hornady reloading tools and accessories. Great for a limited workspace, the Quick Detach system features aluminum mounting blocks for a strong clamp and extreme stability. Cam lock clamps secure the plate with reloading equipment attached to the base. Additional plates are sold separately (MidwayUSA # 909-787). Simply bolt a reloading press, case trimmer or any number of bench mounted reloading tools to the Quick Detach Plate. Then switch gears with ease by simply removing the tool currently in use and clamping the new plate with another tool in place. Mfg: Hornady
