Re: [RE-wrenches] Goofy roofing

[Gordon Woodcock]

Or if you have to be in portrait you can run strut from peak to gutter and
then add your rails to that. A little cumbersome and more material costs,
so if you can get away with landscape it's definitely better.

Thanks,

Gordon

Re: [RE-wrenches] Plastic washers

[Gordon Woodcock]

You can get some pretty exotic polymers if you want to go that route. I've
used Kynar before in strongly oxidizing environments; although, I've never
used it with a PV install. 

On a related note, does anyone have any experience with Dura-Con or similar
products? That might be an alternative to plastic washers.

Thanks,

Gordon
