1. Identifying the two sizes of brackets

There are two frame sizes. One frame is wide and the other frame is thin. Make sure to attach the correct-sized parts to the corresponding frame size. (Use the wider bracket with the wider frame, the thinner bracket with the thinner frame.)

2. Continue assembly

The brackets will fit comfortably in the corresponding frame. Just tighten the screws to continue assembly. In the event the brackets do not appear to align, back out one screw slightly, just enough so that the bracket can wiggle. This allows the two frame sections to align properly so that both screws can be worked in.

3. Slide both sides together

Slide both assembled pieces of the frame together and leave at your desired width.

4. Enjoy!
