BPL Air Core Plus

**Dutch** · 05-10-2007, 09:03

I was showing off to my coworkers with my BPL air plus rated at 1100 lbs and it stretched and snapped lifting 1000 lbs. So I decided to do an experiment. I took an 18 inch piece and tied a larkhead on each end. It lifted 330 pounds ok. It lifted 525 pounds ok. It broke like twine lifting 680 pounds.

It broke at the knot, but the larkshead is an unavasive knot. Also other parts of the rope frayed and showed stress. I would have guessed it would have gone higher than the rated 1100 pounds. Has this stuff let anyone down yet? I think holding 525 pounds should hold me but i was trying to build to 1000 pounds for safety. I guess I'll double it up. Sorry for making this already long thread longer , but I can't figure out how to start a new post.

Peace Dutch

Did it break at the knot every time?

Would you please email BPL with your results and see how they respond? I'd be very interested.

Hasn't let me down yet, but this concerns me.

Thanks, JJ, I appreciate the explanation and not making fun for me.

No problem. I'll wait to meet you so I can make fun of you in person.

i have BPL.com's aircore URSA dyneema, rated w/ a breaking strength of 1400lbs.
http://www.backpackinglight.com/cgi-...ging_rope.html
but even though jeff's been using the slightly lesser rated aircore plus on his hammock, i just can't get myself to trust a single line of something that small

maybe it's because of the few trips i took to the floor

but those falls didn't involve any of the small cord... just a lesser kind of webbing or 1.1oz hammock fabric from the $1.00 bin.
but it is incredibly light, strong stuff (2.6oz/50'). i may use it w/ multiple loops as a hammock attachment.
