roo, i am happy for you to fall on your sword on this occasion.
As I predicted, you have replied and you have attempted to cast doubt on my assertions and warnings.
What a short memory. I believe you yourself mentioned the widespread use of another noose-like hitch (Scaffold Knot) in mission critical applications:
ABoK #409 (Poachers noose) amd ABoK #1120 (Scaffold noose) both function as a noose.
They belong to a class of knots known as 'termination' knots.
They are used extensively by rope access technicians to create 'cows tails' - which are used in life support applications. Cows tails are employed as 'lanyards' primarily for aid progression and secondly for maintaining 2 points of contact while maneuvering at height.
However, these terminations knots are not used as a tie-in knot to a climbing harness.. You have made a serious error here - and you are trying to defend yourself by digging up poorly old posts that actually are ill conceived - you didn't do your home work.
Your assertion that I may have advised the use of 'termination knots' such as ABoK #409 or #1120 as a tie-in knot is manifestly false and I ask that you withdraw that assertion.
The reason why I am replying (again) is that your post is bordering on negligent advice to the public at large. However, I believe that you are safe from litigation in this forum due to the complexities of establishing a link between your advice and an actual user.
You again assert that a 'hitch' can be used as a tie-in knot for climbing applications. This is false.
The gnat hitch acts like a noose. You cannot tie any 'knot' directly to a climbing harness if it cinches tight because it will cause frictional damage to the textile harness material. You can only use knots that dont slip - eye knots that have a fixed eye.
Your assertion that ABoK #409 and #1120 is used for life support is correct but - these noose structures are located at the carabiner end of the lanyard - and
NOT at the harness. At the
harness end - they are attached by a fixed eye knot. Again, this demonstrates that your knowledge is deficient in the subject area of climbing and rope access.
The last segment of your post mentions a carabiner - and this is also
misleading.
A single carabiner attachment directly to a harness is also dangerous and has caused several accidents in Australia and elsewhere. A single clip-in to a harness using a carabiner+hitch is considered dangerous. Carabiners can 'roll-out' of a harness - and they can also become misaligned - both events can lead to catastrophic failure.
Some climbing gyms use a special dual clip-in system but, they are are triple-action locking gates with captive eyes - so they are resistant to misalignment and/or roll-out.
roo - you should cease and desist in any further posts or attempts to cast doubt on my advice. You are digging yourself into a hole from which you cannot escape.
Also, I think if this continues, the forum moderators will shut this thread down.
