Therrin's SRT Rig Also, Tiblocs tear up rope if impacted. It takes force to shred rope, if you don't subject a Tibloc to moderate or violent force, you will not shred rope; two examples:
I use a Tibloc on SRT above my handled ascender to back it up. The single-handled ascender has as yet never failed, so the Tibloc, even though it has been used for years, has never come close to shredding a rope.
Therrin uses the Tibloc above a foot stirrup. It will take his full weight each and every time he stands up on it. If Therrin were shredding ropes, this experienced Arborist would not be using a Tibloc. |
