A44-P Pneumatic Underpinner

Product Reference Code: A+A44P

The A44-P has been designed to be easy to use and it is particularly well suited for assembling medium and larger frames. The A44-P can join all types of moulding with precision using our A+ special steel wedges. Supplied with a tilting floor stand, the machine can be

operated from the front or the back. The horizontal clamp is activated first using the single stage foot pedal. After the two stops are set, a two stage hand lever is then used to position the vertical clamp and the nail head for driving or stacking wedges anywhere along the frame joint.
