Quickdraws are available in a range of lengths to suit different climbing conditions. While shorter 12cm and 18cm quickdraws are often suitable for sport climbing routes, longer quickdraws are essential for wandering routes to reduce rope drag. When trad climbing, longer quickdraws help extend the sling on your protection, reducing rope drag and ensuring that any force on the protection is in the desired direction of pull. Alpine draws are commonly made with two carabiners and a 60cm sling, allowing even more extension for severely wandering routes or to reduce rope drag through an overhang.
