These mid-clamp are for mounting the semi flexible frameless or thin film solar panels that are sold on eBay.  (If the solar panels flexible enough so they can roll up, these clamps will require modification to work with these panels.)  The mounting brackets are approximately 8 cm long. 

Hardware is included for the UISolar Rails.

I will combine shipping where possible for all hardware such clamps, and splicers but not with the rails as they can't ship with hardware.   If combined shipping is possible, I will refund the difference if shipping is greater than cost. 

Here is an example of the panels these clamps are designed to work with.
