Zhengmy 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(10 Pack)

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

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.

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

If you want to use these with super strut, you must buy appropriate strut nuts. I enlarged the bolt hole to use the common 3/8 super strut stuff, and also bought new larger allen head bolts (regular Bolts will hit the bracket, not allowing it to turn).I knew this going into my first solar project. Seems sturdy, but I wonder how they would handle 75mph on an RV.Item is exactly what I ordered. No complaints.

Fits perfectly and holds panel down tightly.

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.

Worked perfect for my array.

This fits the Renogy panels perfectly.
