There was an article posted on the BD website last month on how to connect 2 slings. Interesting test results...

Interesting read. Thanks for posting.

Thanks, useful info.

Nothing really new here. If you are girthing slings together you better not load them much. Clip them together with a biner and they stay full strength, and in our informal tests, the biner will break before the webbing.

One more knot to play with. I'd never seen a "Climbing Hitch."

Thanks

I remember seeing a report about a Mammut dyneema sling breaking at a knot under body weight several years ago .. googling ..

Very interesting and thanks for posting.

Assuming that you have the extra biners, wouldn't it be better to connect the slings with 2 lockers, with the gates facing in different directions?

Interesting.

I'm not a climber, but I do use long pieces 0f 4000 lb test tubular webbing as handlines (it is amazing what we have done with a 50' piece and a biner ;^)).

Some years back, I set up a handline in a chute for a partner. The chute was about 20' high, so most of the handline length was just sitting on the sloped ground below. When she cleared the top of the chute and started heading up the next bench, she set off a fall of several hundred pounds of sharp limestone fragments. We later came down with the same handline, and another friend coiled it and handed it back to me.

What I didn't realize, is that the limestone fragments, falling from about 50' above, had nearly severed the lower part of the webbing in three places, where it was resting on the ground. In fact I didn't see the cuts till I was later uncoiling the webbing for another use as a handline and running it through my fingers.

If you've got a locking biner, it's redundant to use two with opposed gates. You'd do that only if you had non locking.
