Home Depot equipped sport routes

Ill start by apologizing for bringing a professional approach to a hazard assessment to a recreational issue.

The user that brought forth the observation that Sitka may have made a unit conversion mis calculation is very likely correct and that is a really good catch if so.  However there may be a secondary explanation.  There is equally a chance that the spec sheet is correct and the chemical composition of the adhesive for direct to consumer use has been altered to meet regulatory compliance in the USA (example- many items are altered to be able to be sold in California).  If the spec sheet is incorrect this would be significant oversite on behalf of Sika.

Yet again I will re-state that the U-Bolt pictured is inconsistent with what the package reads.

There are very concerning data and documentation issues that plague both the bolt and the adhesive.  This is a point of concern to me, however I have noted that it is not a concern shared by most.

This maybe helpful. “The U Bolt”

Cashmab, what is the expiration date on the glue? Was the glue stored in a temperature controlled environment? Are these going to be installed near Boston or elsewhere?

Both products show a severe lack of quality control and documentation. Home Depot/Everbilt does not manufacture their products, they source them from undisclosed manufacturers and provide zero documentation that any quality control has been done. The legs of the this U-bolt are narrower than the CT u-bolts and are only 1.4" apart, center to center. When you're drilling 10mm holes, the sides of your holes are going to be just less than an inch apart.

For me, the largest issue is that you are drilling twice as many holes in the rock as is necessary, with minimal strength gain due to the narrowly-offset legs. If using Home Depot products, with zero proof testing, for bolts on a climbing route feels wrong to you; it is probably because it is wrong.

Edit to add:

Cashmab, I would have your friend return the items to Home Depot and get the cash. Both products are clearly not as advertised. I suspect that is why they were not used on the jobsite. These $12 U-bolts are sold as 316 stainless (online shows nuts should also be 316), but you clearly have 304. The $30 Sika AnchorFix2 advertises as being suitable for outdoor use, but their own 2020 product data sheet clearly states it is not. After your friend returns the items, you can buy high quality climbing anchors with quality control. Here are the archived docs/websites that you can copy/paste into address bar.

These are glue ins, not expansion bolts.  Two legs an inch apart is going to be significantly stronger than a single leg bolt of equal length and thickness (like Raumer Antrax for example).

Sure, Everbilt is a house brand with various manufacturers, and not everything branded everbilt is the absolute best value, but this is just a steel rod bent into a U with some threads on it.

Yes, with regard for your professionalism and commercial concerns that are reflected in your fine products, we don't need to overthink this one.

Seaside? Let the overthinking begin but in a reasonably dry place for the bolts without extraordinary corrosion concerns it's not complicated.

This of course is the opinion of an old curmudgeon that has used an example or worse of every horror show ever shown on this site :).
