FYI for Eco-Worthy Dual Axis (or similar) rails, these will not work due to the 'pincher' being too narrow to clamp. I was able to use the blue clip and nuts with the panel clamps fine (on lowest setting) fine.

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.

Very easy to adjust to the thickness of your panel however the only thing to keep the adjustable part in place is a small rubber band. My panel required the minimal expansion slot to fit and that was not enough to where I could get them real tight (I installed my on a piece of plywood to use on the top of my boat T-Top). A little chunk of some super double sided tape (alien tape) was a great solution allowing me to get all of the clamps to tighten on my panel. Kit came with really nice fasteners for use on a Normal rail system for panels, they just wouldn’t work in my particular installation method. Great value for the price and exactly what I needed.

easy to use perfect

Ok first off these are not thin aluminum they are very durable. Next off (These will not fit standard 1-5/8” uni-strut) Without a washer added to the fitting. The bottom nut is not made for this strut. I believe there is a thin narrow cheaper aluminum strut but if mounting solar panels which is what these were made for i personally wouldn’t use cheap strut. These are height adjustable but i am using 200W Renogy panels and i have to use the lowest adjustment but they will hold down tight. Because they don’t say specifically in the description they won’t fit Uni-Strut is why i am giving 3 stars. I still recommend and would buy again although they probably make actual ones designed for uni-strut but i was unable to find them on Amazon.

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.

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