This is the answer to "How are we going to hang a light THERE?" This versatile clamp with adjustable jaws will let you place a pair of 5/8" baby pins just about anywhere you can think of. The jaws open up a maximum of about 3.5", and the soft rubber nubbins on the clamp jaws are both gentle on a surface and yet provide a tenacious grip. Kinda like a pitbull with no teeth. Or something like that.
