7009 Alfamacchine U200 Foot Operated Underpinner

Foot Operated Underpinner for Quality Bespoke Framing

Expertly engineered by Alfamacchine to become the bestselling foot operated underpinner in the world. The thoughtful design and very high build quality delivers professional results with ease.

Includes full boxes of 7mm, 10mm & 12mm V Nails.

Double Piston Clamping Mechanism

The double piston clamping mechanism evenly distributes pressure, particularly helpful for working with hard woods.

Joins Mouldings Up to 130mm Wide

Multiple V-nail insertion positions allow moulding to be joined up to 130mm wide. For best results, we recommend adding the optional U200 Moulding Support Wings, 7012.

Two Way Operation & Table Tilt

Set up is intuitive – choose whether to work from the front or rear of the machine; quickly adjust the angle of table tilt. Working from the rear is easier when joining larger frames.

Spring Loaded Pull Pin Mechanism

Quickly adjust the top clamp to suit the height of the moulding. This makes it easy to set the machine to different moulding profiles, reducing the capacity for error. Suitable for moulding up to 80mm height.

Cable Pulley-operated Pedal Actuator

Powerfully inserts v-nails with minimal effort. It also offers good feedback allowing the operator to feel when the v-nail has been fully driven in. Pedal height is adjustable.  

Unique Power Twist V-Nail Driver Assembly

Provides trouble-free operation up to 1 million cycles. Switch between v-nail sizes in seconds. The U200 uses Alfamacchine’s Power Twist V Nails which have a patented tapered shape to pull the join tightly together. 

Fixed Back Fences

The fixed back support gives the user confidence that no adjustment will be needed.
