This is a brand new, unused Climbing Technology UP LOCK double pulley (2P672). I purchased it new in April 2025, but I no longer need it, so I would like to sell it to someone who does. This UP LOCK has a releasable cam locking function, so if you also have another double pulley (like the UP ROLL), you can create a 4:1 or 5:1 system. It is unopened and unused, so I don't know the details or how it works. Please refer to the Climbing Technology website for information on usable rope diameters and other details. Since it is new and unopened, I will ship it as it is, in the plastic bag shown in the photos. It has been stored at home, so please refrain from purchasing if you are sensitive to this. Thank you for your understanding. The following is a translation from the Climbing Technology website: Key Features: ・Light alloy side plates and pulley with anodized finish, cast stainless steel cam. ・Pulley mounted on ball bearings. ・Equipped with a free-lock system that allows the cam to be unlocked or locked with one hand, even when wearing gloves. ・For use with 8 to 11 mm EN 892 or EN 1891 ropes, or Ø 8.0 mm EN 564 cord.
