Emergency Ascender – rope damage?

Actually I meant “new” as in brand-new, not-yet-broken-in. The BW rope is quite small and slick before it gets broken in, and getting the tibloc to stick to it is challenging.

The small ascending tool most known for tearing up ropes is the

Petzl Tibloc. I have used it a lot on small ropes in the last

couple of years. It will work on 8mm ropes consistently, even

Canyon Pro (which tends to be a little small), if used with care.

New Canyon Pro – very difficult – requires careful setting of the

Tibloc on the rope with each placement. Tibloc on 8mm static rope

requires a FAT ROUND carabiner like the Petzl Attache to work.

But, static ropes are firmer than dynamic climbing ropes, and I

could see it being very difficult to set consistently on 8mm

climbing ropes.

When the Tibloc “fails”, it slides down the rope with the teeth

tearing up the sheath. I have not had big problems with this, but

others have.

ANY small ascending tool can damage the sheath (some) if it slips

when weighted. But, most of them will make only very tiny damage,

at body weight. The spring on the Ropeman will wear out, and I

found it necessary to squeeze it onto the rope when weighting it,

for the last few months I used it.

The Duck looks cool.

At body weight, ascenders, large or small, do not damage the rope,

unless your try quite hard to do so. I believe BDC has torn up a

rope with a tibloc, while hauling a pack and having misfortune.
