MageClamp Standing Seam Metal Roof Clamp for Solar Panel Module Mounting Racking Pack of 10

Update 12/14I bought 60 more of these, by far the best deal around, especially given the super solid quality!These are intended for thick brackets (1/4: etc.), let them know if you need to secure thinner clips and they will include shorter top screws. Or use zinc or stainless washers.Original ReviewTop notch quality and very sturdy construction, Milled out of a single solid chunk of aluminum - very nice!The bolts may be a bit long if you're attaching thin material to the clamp. Either use some extra washers or shorter bolts.

I bought them just to find it only works if your seam is completely even from top to bottom, my seams are wider at the bottom then the top, so when you turn the screws on the clam it glides right off the seam. I had to cut the side opersite the screws in an angle to make it work.

With a slight delta shape that is wider at the bottom than top of the standing seam, these parallel face clamps drive themselves up off the roof. A sharper point on the set screw might fix that.

These were a horrible fit for my standard standing seam roof. I had to grind down about 1/8” off the inner channel and another 1/8” off the bottom foot that didn’t have the lip. Once they were on they worked fine but they needed some significant rework

...they were way to small to fit my seam. I called and was told to put them on the other way around. THEY ARE STILL TO SMALL TO FIT OVER THE SEAM!

i only took a few minutes to fix brackets and plates for stops.

The top bolts for the wire clips are a 1/4" too long. With the bracket mounted to the roof ridge there is no room for the bolt to protrude into the bottom of the bracket

Great fit and match, good quality, very easy use.

Clamps do not fit my roof. trying to return and company has not replied in a month. Thank you for being professional.
