Slow Pulling a Webbing and Cord Girth Hitch

While pull testing anchors we broke some old equipment to see how strong they would be. Shown here are two slow pull tests including: a 1" tubular nylon webbing loop girth hitched to a 1/2" diameter screw link, and a 6mm PMI accessory cord loop girth hitched to a 1/2"diameter screw link.
The webbing girth hitch broke at 25.6 kN (5744 lbs) and the cord girth hitch broke at 16.1 kN (3625 lbs).
For additional research and data on climbing and rescue gear and system strength, see the SARRR web page at: sarrr.weebly.com/

Thank you for testing this.
Do you know what the 1" tubular webbing rated at in a straight pull? The sewn ones I have a UBS (ultimate break strength?) of 7,000lbs or 31kN.
The sterling 1" tubular webbing I have is 4,000 lb MBS in a straight pull or 6,100 lb MBS in a sewn loop.

Sorry, I just saw this comment. Way too late, I know... I haven't pull tested webbing off the spool. So I don't know. It is rated at 4000 lbs, but it probably breaks at a much higher strength.

cavertevans Interesting thanks
