Chris, As only the threads of all SS bolts need anti-seize, there's a much neater method. Anti-seize is available in a solid twist-to-extend tube that is neat and easy to use. One light swipe across the make threads of each bolt - doesn't take much to prevent galling.

Our house is on the ocean, in the Caribbean. If you are using something like SnapNRack, where a stainless bolt goes through an aluminium channel nut, use Permatex or it will seize. Other than that, I have not seen racking corrosion in eight years on the roof. Put all the clamps, bolts, nuts etc,

We just had that same concern, but once you torque the connection down there was no noticeable movement. As someone else mentioned the plastics can be tough to hold up to UV, temperature, compression, and thermal cycling. Once that hard plastic cracks and falls out, you definitely will have a

My hesitation to that is the compressibility of the neoprene. One of the things I like about nylon or similar hard plastics is they don’t compress so you do get a ridged structure. jay peltz power > On Jan 28, 2016, at 10:15 AM, Ray Walters wrote: > > I would use a SS washer with integrate

Hi Larry I wasn't planning on installing anything between al and al. Just between SS and al. So the module will still be bolted directly to the al rack material. I'm not too worried about the grounding, and certainly not worried enough to install lay in lugs with copper to each module. As lon

Hey Jay, I’m still trying to picture this and had a thought: If you isolate the module from the rack electrically with these washers, and both are grounded, and the two grounds are not at the same potential (different length ground runs), you may be creating a path for high voltage into the arr

One thing I have noticed is that many rack materials are a mixture of aluminum and other metals. I found out when trying to weld the material. It would be good to know just how dissimilar stainless is compared to the rack metal. Jay, I would ask them what good is the insulator if the bolt/screw
