Zhengmy 10 Solar Panel End Clamp Mounting Z Bracket Mid Clamps Aluminum Rail End Clamps Clips Adjustable Panels Grounding Gutter Kit for Pv Mounting System Install Hardware Fasteners Accessory

Use only for the newer thin panels. The bolts are too short for the old style solar panels. Had to order new longer bolts to make them fit

These end clamps work great they are adjustable to fit most any thickness solar panels. It took a couple of minutes to get it figured out but once I got the hang of it had my ends all attached they work great and if I need more in the future I will repurch them. I highly recommend them.

I really like these, no complaints whatsoever.

As others have stated, the nuts are too small for Uni Strut (aka strut channel or Superstrut). The nuts with these clamps will literally pull through the strut opening. You need the nuts that are made for the struts you pick up at HomeDepot, Lowes, Menards, etc.. Fortunately I did have an Eco Worthy ground mount kit laying around and was able to use those. The clamps are 5 stars, but the description should be updated for US sales, at least. Sizing diagram doesn't clearly show the nut size and the sample mounting pics show strut - but must be smaller.

Well-made brackets. The adjustable height feature is nice to have. Good value for the money.

These are a cheaper version of the previous ones I purchased. They will not tighten down the 30mm solar panels unless you bend the aluminum top part. If you don't mind that extra step then these are for you.

I used two lengths of unistrut as rails and these along with others and it turned out great. They hold great no getting lose at all after 3 weeks of driving

I bought these adjustable height, extruded aluminum clamps to hold down some really old Solec model S-4233 solar panels. From the seller's details, it looked like they might not fit around the aluminum side railing of my panels but I took a chance and they do fit.
