AMP U-400
Formerly called VN144S

The U-400 has been designed for ease of operation and is particularly well suited for assembling larger frames. This machine comes with a height adjustable base and has a convenient tilt / roll feature which allows for easy movement around the shop. It can be operated from the front or back and has a dual stage foot pedal which allows the framer to see if the corner is properly aligned before nailing. After the framer sets the stops, the hand lever is then used to position the nail head for driving or stacking v-nails anywhere along the frame joint.

Features of the U-400:

  • Can accomodate molding up to 5 1/2" wide

  • Utilizes vertical and horizontal clamps

  • Table tilts easily and has an adjustable height for comfortable operation by any user

  • Adjustable fence allows joining of 4, 6 or 8 sided frames

  • Can join frames from either the front or the back of the machine

  • Uses an arm instead of pedal to insert v-nails allowing accurate positioning for inserting or stacking v-nails
