1.06 Inch Solar Panel Bracket Aluminum Solar Mid Clam with Mounting Brackets 32-50 mm Clamps Adjustable End Panel Clamps(56 Pieces)

Good quality aluminum and stainless parts, but the end mounts are not designed for thinner 100W panels or Uni-strut U-channel type rails. They can be made to work with a thin shim and swapping out the retaining nut for the rail anchor, but just know that they are not a direct fit and are designed for a different rail type. The middle mounts however work great regardless of rail or panel thickness and can attach to any uni-strut anchor/bolt combo.

some people in the reviews are complaining that there are not enough bolts or the retainer nuts don't fit unistrut. buy your own unistrut sring nuts and your own bolts and washers. this is an excellent product!

The end bracket is nice that it is adjustable and works well. I had to get washers to go in the strut channel rails as the included nut is too small for standard strut channel.The mid-brackets do not include any bolts, so be prepared to go to your local hardware store for these.Overall - not bad - I would use these again.

Works greatI had to replace bolts and track nuts for unistrut hardware and 1/4" bolts

Don't come with screws for the middle panels

Exactly what I needed to complete my DIY solar panel installation using my exiswting aluminum rails.

After contacting the manufacturer/seller which told me these brackets would work, the nut that secures the brackets slips through the Unistrut. The manufacturer/seller knows this failure. All their drawings that show dimensions never show what size the nut is. Not usable for Unistrut unless a fender washer is used but you then sacrifice strength and grip of the connection. Do not use.

I use these on all of my roof mount and some ground mount installs. I got tired of ordering the wrong depth based on different PV panel thicknesses. These adjust to any size panel I have used to date. Much less hassle.
