That's the only pic I have but maybe I can explain it better. The top and bottom square frames are 40" wide and 30" long. Attached to one another by a T shaped connector and an elbow one to connect the poles going down which are 22" in the front and 30" in the rear to make it tilt. The clamps we bought at Lowe's, they're called spring clamps. Found them in the tools section. I hope this helps.
