The U-400 could be operated from the front or back and has a single stage pneumatic foot pedal that activates the Horizontal Clamp, securing moulding during the joining process.
After the framer sets the two position stops for measuring the max distance between strokes, a dual function hand lever is then used to position and actuate both the Vertical Mould Holding Clamp and the V-Nail driver inserting V-Nails anywhere along the pre-set stroke distance.
A key operating feature for the U-400 allows the operator to quickly change V-Nail mm size using an interchangeable metal magazine channel. Operator easily accesses the interchangeable channel from the rear of the machine to load the appropriate V-Nail size. This feature eliminates the added purchased cost of plastic nail cartridges.
