What is it used for?

Offset clips are used to secure your image inside the frame when the rabbet is not deep enough to hold your components and they stand out over the edge of the back of the frame. Offset clips come with screws.

How do I use the canvas clips?

Note: Offset clips are in the shape a weird looking S.

Place your frame face down on your work station. Measure approximately three inches from inside corner of frame and screw the offset clip into the frame. The other end of the S lays over your image component. Push it down, or bend it up a little to firmly secure your image component in place.

Place more offset clips approximately three inches apart all the way around your frame.

Also, if you use glass, only use two offset clips per side, then check to be sure you removed all the lint from inside the glass. More than likely, you will find lint the first two times you check. Once you are sure you have removed all the lint, finish placing the offset clips around the frame.
