Re: [RE-wrenches] Snapnrack end caps
Hi Drake, I can confirm. The design could be improved. I’ve noticed that end caps on rails that are flush or a fraction of an inch shorter than the panel frame lose the end caps at a higher rate than when the rail sticks past the module frame. My guess is that module movement from expansion/contraction is popping them off.

Re: [RE-wrenches] SnapNrack
Good points Ray. I always warn the crews of galling and to avoid spinning the SS hardware to fast. Another tip is to try to keep the SS hardware out of direct sun prior to using it.

Re: [RE-wrenches] SnapNrack
With all this talk of anti-seize in an email thread with SnapNrack as the
subject line, I just wanted to add another comment which is that we have for
several years now shipped all SnapNrack hardware with a wax coating. This
significantly reduces issues with hardware galling even when anti-seize is not
used at all. The coating process on the black hardware seems to even further
reduce galling. We still recommend application of anti-seize as a best
practice but I suspect that 90% (or more) of installs go in without any and
feedback from customers on hardware galling has gone down dramatically since we
rolled this in. Perhaps we should promote it more -

Anti seize also comes in larger cans with a brush, but it still can get messy.
Also on the torque issue, I found just using the T handle hex wrench from the
manufacturer (we use S Flex) gets the torque where it should be, and even a
gorilla can't over torque it too far.
Old fashioned, but we have less heavy tools to carry on the roof, and no over
torque issues. With lubed threads, the T handle wrench can twirl, which is
almost as fast as using a power tool.

Esteemed Wrenches,
Does anyone know of a less tedious and messy way to lube the bolts than
squeeze tube anti-seize?
My 2 cents; I believe that the torque specs for an engineered assembly are put
in there for a reason. Ignoring them puts the installer on the hook for any
failures. Aside from being the right thing to do, using torque wrenches helps
avoid assuming unnecessary financial risk which my thin margins cannot afford.

Using a cordless impact driver and no lube can cause not only module damage

Re: [RE-wrenches] SnapNrack
Hi Benn, The Alpha+ mid clamps are unique, in that they have mini hex head set screws epoxied into place on the top of the mid clamps, with their sharp little points sticking down to bite into the top of the module’s frame. One of these small set screws was sticking out about an 1/8”, not good, all the rest of them are set at less than 1/16” more like a 1/32”. After it shattered the glass we figured out what had happened, and really started to pay attention to this factory glued in grounding point carefully! That is why I’m wondering about the UniRac’s mid clamp bent down points and the degree of tolerance that UniRac bends these to. Hand torqueing is the best bet for sure, although in the case of this mid clamp it never got close to torque spec when the module’s glass shattered.

Re: [RE-wrenches] SnapNrack
I may be a little biased but just wanted to weigh in quickly on this thread: - with the merger of SnapNrack and SunRun there has never been any intention of private labeling the product line. We heard this concern a lot when the merger first happened, but that was almost a year and a half ago - we don't hear it too much lately. - I have personally run many load tests on SnapNrack mid clamps, we run them to over 2,000 lbs and you can't even tell they have any load on them. That load corresponds to over 200 psf of uplift on a typical module . . . so they have a healthy safety factor and I believe that if we were to benchmark against other mid clamps we would be among the strongest in the industry, especially with the addition of bonding pins last year as part of our UL2703 listing.

Re: [RE-wrenches] SnapNrack
So far, so good. No issues like that. However, on one job we had a problem with the bolt heads not catching in the rail channel and modules popping up. I chalked that up to an installation error by an installer that was easily resolved. Despite the convenience, I'm not a huge fan of t-bolts for top clamps. Square head bolts that you slide into the channel seem much more secure and less prone to error. However, the bonding feature makes the T-bolts worth the tradeoff.

We had a situation where an extra square head was left in place under a panel. It must have been thought to be more trouble than it was worth to remove. 10 year later...Crack goes the Sanyo! Installer error, we had to do the right thing... it hurt!

However, on one job we had a problem with the bolt heads not catching in the rail channel and modules popping up. I chalked that up to an installation error by an installer that was easily resolved. Despite the convenience, I'm not a huge fan of t-bolts for top clamps. Square head bolts that you slide into the channel seem much more secure and less prone to error. However, the bonding feature makes the T-bolts worth the tradeoff.

Re: [RE-wrenches] SnapNrack
We standardized on snap and rack about 3 years ago as well. Previous to that we used a number of systems unirac, iron Ridge etcetera. Good hardware and easy to assemble. We recently installed our first Snap and Rack residential ground mount. That installed very nicely and it priced out better than the UNIVRAC ULA. The online configurator for the residential ground mount has a few bugs. A call to snap and rack tech support resolved the issues and they ran the configurations thru their internal tools to verify measurements. They were very accessible and helpful in their response.

Re: [RE-wrenches] SnapNrack
Good point, Jason. I like Snap N Rack's products, but when I tried to order equipment (no distributors carry their stuff in Colorado) they never returned my calls or emails. I'd certainly be wary of their future support, if they won't even return calls for sales. Frankly I'm going to start calling out ALL manufacturers that don't back their product, or otherwise don't treat us RE Wrenches with respect from here on out. Manufacturers' reps on this list be forewarned. I'm getting too old, and worked to hard in this industry to pull punches now, and I don't think I'm doing my fellow wrenches any service covering up for the manufacturers' mistakes any more either.

Re: [RE-wrenches] SnapNrack
You tell 'em, Ray! I'm having an off-list conversation with another Wrench about IronRidge's new IGS system - and supply issues that left us with tons of rail and no module mid-clamps. What a disaster. While many have moved away from Unirac, we just moved back. Although they have had supply/distribution problems over the years, they've been overall reliable and stable, even after being acquired. On the other hand, don't get me started about their lack of an ASCE 7-10 compliant installation manual for a long time after it was required here. I really didn't intent to blast any particular manufacturer, but looking at the big picture I have to consider with whom I'm getting into bed. These acquisitions are worrisome in that respect.

It is my favorite. My crew said they would mutiny if I changed back to others we have used.

Re: [RE-wrenches] SnapNrack
Hands down my favorite to use. Ditto what Daryl says. Wire management is a breeze. Stamped engineering for my state makes the AHJ happy. Clean lines. My only gripe is that the ends of the rails tend to be VERY tight making it tough to install their universal end-clamp if you are in a precarious position on the roof. I use my linemen's pliers in reverse to spread the ends out before sending them up. 3 years of use and this is my only complaint.

Re: [RE-wrenches] SnapNrack
We just serviced an old SnapnRack install, and we found the usual: most of the mounts had been over torqued and the SS bolts had spalled. With a bottle of anti-seize and a torque wrench we replaced the damaged hardware and all went well. I like the end clamp that grabs the module from underneath, and I agree with Daryl about using the open rails for wire management. Unfortunately we don't have a local supplier for SnapNRack, and when I contacted them directly, they never returned my call.
