Manual Underpinner

Product Number: 178720006

The U-200 is an entry-level frame assembly machine for any small retail operation. As a fully manual machine, it requires no compressed air or electrical power to operate. This unit allows the framer or graphic shop owner to bring the joining operation in-house for cost control and quick customer turn-a-around.

The U-200 is compact, quiet operation and has a small footprint. Our lightest and most portable joiner, it can be easily moved from place to place in your business environment. It can handle moulding sizes up to 5 1/8” (130mm) wide and 3 ¼” (80mm) high, offers a tilting base with front or rear set-up and a “positive placement” clamping feature.

Enjoy years of trouble-free operation with Alfamacchine’s unique V-Nail driver assembly designed to eliminate frequent blade changing.
