Climbers will clip a carabiner probably thousands of times across its lifetime, but how much do they actually know about where it comes from? In November last year, (2014), we travelled to the headquarters of British climbing manufacturer DMM to find out for ourselves exactly what goes in to the production of a carabiner. Over a day in the factory, we traced the production of a carabiner from the arrival of simple aluminium rods all the way through shaping, forging, heat treating, cutting and all the way to anodising and lasering. Check out the video to see the ins and outs of the production process from start to finish.
