Petzl Accessory Cord - Prusik Cord 7 mm

This Petzl 7 mm accessory cord is designed for use in mountaineering and climbing when you need a reliable static line, such as making prusik loops, hauling gear or backing up anchors. It’s a straightforward solution for tasks where you don’t need dynamic stretch but do want secure handling and compact storage.

The slim 7 mm diameter gives this cord a good balance of flexibility and grip, making it easy to tie and untie friction hitches that hold firmly under load. Its static construction means it won’t stretch significantly when weighted, so prusik knots stay consistent and hauling or lowering gear stays predictable.

Static ropes like this one have minimal elongation compared with dynamic ropes, so they don’t absorb shock by stretching—ideal for fixed lines and gear hauling. The 7 mm thickness provides enough surface area for a secure bite in friction knots while keeping both weight and bulk to a minimum.
