I am selling a set of three carabiners, imported directly from a US arborist supply distributor about 7 years ago. I used them for rope climbing about 20 times after purchase, and they have been stored indoors since then. I no longer have a use for them, so I would like to offer them to someone who wants them. The details are as follows: * DMM Double Locking Carabiner * Model: WALESUK A880 * MBS (Minimum Breaking Strength) in normal use: 28KN * Safety Standard: CE0120 * CT (ITALY) Screw Locking Carabiner * MBS in normal use: 23KN * Safety Standard: CE0639 * Black Diamond (USA) Screw Locking Carabiner * MBS in normal use: 25KN * Safety Standard: CE0639 Please understand that these items are used and consider using them at your own risk.
