The P13KUE autofeed screw system comes with a removable universal extension that provides the flexibility of a two-in-one unit. Besides using the unit as a standard shorter length tool to screw 1- to 3-inch screws, with little tool configuration it can be fitted with a long extension for added value. This gives the user capabilities to use the tool in a standing position to minimize fatigue and strain on the joints or back. For applications requiring a shorter length screw gun, the extension of the tool can be removed, making it useful for drywall, roofing and fencing.
