I've used this for installing solar panels on my roof.. i'm 240 lbs and it has worked for me perfectly. I have not had a hard fall on it.. but seems like it'd hold me no problem.

I have ordered several Singing Rock Route 44 ropes before and found those to be outstanding. My latest order of the Orange 150' 11.2 mm rope, however, had two issues. One relatively minor the other major. First was the rope manufacture date. I ordered in April 2018, the rope I received was manufactured in March 2017 "“ over one year old. One year effectively reduces the working life of this rope by 10% as working life is reduced approximately ten percent for every year the rope is stored unused. The rope I received was indeed unused, but it was not newly manufactured.

The second issue also is related to my latest order mentioned above. The issue has been with two Singing Rock Route 44 150' ropes received from the same seller through AMAZON. The first rope (my April order) was replaced by the seller and the replacement had the same issue. A portion of that first rope I received had striations that ran diagonally across the rope along a four-five foot length, about 60 feet from one end of the rope. The striations occur because the rope has several strands that have been frayed in a diagonal pattern. Running a friction hitch along this section of the rope caused the hitch to "stick" and resulted in exposure of the inner white core of the rope. The hitch ran fine along other non-affected sections of the rope. This rope was replaced with a second rope. Removing it from its bag and inspecting this second rope revealed the exact same frayed pattern (diagonal striations). As with the first rope, these diagonal striations occurred in a 4-5 foot length once again at 60 feet from one end of the rope, but also occurred at 50 feet.

These defects are unacceptable for life support equipment. Attempts to contact the manufacturer proved unfruitful. After successful initial correspondence with the U.S. distributor asking for inspection of samples of current stock to determine whether the issue is systemic or confined to a certain lot, follow-up requests for updates have gone unanswered.

The problem might be associated with a certain lot, I don't know. And I may order again since I have had good success with the ropes in the past, but will likely wait a while.

ALWAYS inspect your ropes prior to use (!), especially if they are to be used in work that may pose a danger to life and limb.

Very strong rope. Rated at 32 Kilo Newtons strength or about 7800 lbs. I put it on my main sail halyard. Much stronger than the double braided nylon I had used.. Very smooth with low stretch,

Ordered the 600' rope. Used for several rappels so far, seems to be holding up quite nicely!

Purchased 10.5 mm x 200'.

Initial impression: The package arrived ahead of anticipated, in excellent condition and well wrapped and boxed. The customer service was great. I got a reply earlier than amazon suggested and enjoyed the response to my early shipping request.

I was surprised to find the rope's material very maliable. Not stiff, like previous lines. I chose 10.5 mm because unless you're using it for tactical high load rappels you wont be getting full use out of a +11mm. Even 10.5 mill may be much but i tend to ware my lines down prematurely as I like to put a lot of heat on them due to speed.

NFPA (National Firefighter Protection Association) means it meet the national specifications that designates the item safe for fire agencies to use in rescues. A plus for me.

I hope the shell fibers hold up since i will be beating it up in the Grand Canyon region quite a bit.

Update on its use to follow...
