Underpinners - Frame Assembly Machines

MP | Single Channel Underpinner

Our U-500 is recommended for high-volume production facilities that require the primary use of a single sized V-Nail for frame joining. The U-500 has the same user-friendly, touch screen interface as our U-600 Underpinner. The only difference between the two models being the U-500 has single channel capacity compared to a multi-channel with the U-600 unit.

With data storage of 5,000 different frame profiles, the operator can easily recall any frame profile alphabetically, numerically or by using the bar code reading option.

Handles frame joining requirements commonly found in picture framing, woodworking (Door Trim), canvas stretcher bar and mirror frame joining.
