Workings of a carabiner
A carabiner, is easy to use, one part is hinged and the hook can therefore be easily opened by pushing on it with the thumb. Some hooks include a nut that can be used to secure the hinged portion for added security. The carabiner is very strong because a closing is made when the hook is 'closed'. Almost all carabiners have a spring so that the hinged part remains closed, except when pushed open.
Our carabiners are sold in sets of 10. We have 3 colors of the plastic carabiners in stock. We stock 10 different colors of the metal types: light blue, red, light green, purple, yellow, dark blue, pink, black, orange and black/orange. In addition, we sell a mix set: a set consisting of 10 hooks in which all 10 colors are represented. It is possible to make your own combination of colors (with a minimum of 10 hooks in total), for this you will have to send us an email. Depending on our stock we can combine anything.
Otto Herzog, a German mountaineer who lived around the year 1900 had the nickname "Rambo" because he was always tinkering and kept hammering on all kinds of problems ("Rambo" is an abbreviation of the German word "Ramponieren", which means to hit and pound). At the time, the Munich Fire Department was equipped with pear-shaped steel links, and Rambo saw a possible application of these steel links in mountaineering. Otto Herzog then invented the carabiner.
The result was a hook specifically for climbing - a steel loop with a quick-opening section. This invention solved two problems: it greatly improved safety by eliminating the need to detach the climbing rope from the climber, and in addition the carabiner was faster to use, allowing Herzog and other climbers to push the limits of rock climbing and try more difficult, longer routes.
