AMP Underpinners & V-Nails

Underpinners are used in wood picture frame assembly. Whether you need an entry-level machine or something a little more fully-automated, the U-Series of AMP Underpinners are designed to meet the needs of any size production. 

AMP Underpinners use patented Power Twist® V-Nail technology to pull your joints tightly together, ensuring the strongest holds for your framed art or canvas stretcher bars. AMP V-nails are manufactured from a high quality steel and coated with proprietary silicone to allow smooth penetration into the joining material.
