Used only once and hasn't been used since... It's in almost new condition. This is a lightweight and compact ascender that can be used as an alternative to friction knots in rope ascents, hauling, and self-rescue. The "TIBLOC" uses the rope being pinched between the carabiner and the device to provide a braking function in any position. - Brand: PETZL - Model: IBLOC - Color: Orange - Material: Aluminum ・Can be used as a self-jamming pulley in rope ascent and hauling systems. ・The system automatically pinches the rope between the carabiner, providing a braking function in any position. ・Easy-to-understand illustrations are engraved on the side for setting the rope. ・The stainless steel cam with angled teeth has a slot to remove debris, and functions even with muddy or icy ropes. Thank you for looking.
