| Summary: | early twistlock from originator of the twistlock |
| Description & Commentary: | This design is one of the earlier twistlock carabiners. Clog produced the first twistlock carabiners, with advertisments appearing in 1983. These ads show drawings with a sleeve design using diagonal knurling and a 90 degree throw, whereas this example has straight knurling and a 120 degree throw. See also: twistlock D with straight knurling and 90 degree throw. As with most modern autolockers, the hinge pin includes a lug to guide the locking mechanism. Notably, this is much larger diameter than found these days. |
