Petzl Rollclip Z Screwlock
Interesting integrated screwgate karabiner with efficient ball-bearing pulley. The new layout facilitates easy clipping of the karabiner to ascenders, which makes it more practical for caving use. The most obvious uses for the Rollclip are: light tyrolean traverses on rope; creation of Mao/ counterbalance system for rescues and lifting heavy loads; and as the attachment of the lower/inverted ascender in a Z Rig / 3:1 hauling system. Teams up well with a Micro Traxion for a compact and lighweight rescue package.
Given weight 105g. Gate opening 21mm. Works with ropes of diameter of 7mm - 13mm.
Working load of the pulley is 4KN. Efficiency 85%. For the karabiner, major Axxis strength is 20
KN; minor axis 8KN; and gate open strength is 7KN.
