Attach the pouch
The chain on a tool pouch is typically used to attach the pouch to a larger tool bag, belt, or waistband. This allows the user to keep the pouch within reach and quickly access the tools inside without having to take off the larger tool bag.
Distribute the weight and reduce stress
The chain can also help to distribute the weight of the tools more evenly and reduce stress on the larger tool bag or waistband.
Some tool pouches are equipped with T-shaped metal chains for carrying tape.
Some tool pouches come with a detachable chain, allowing the user to choose whether they want to use it or not, depending on the specific task or job. The chain on a tool pouch is a useful feature for anyone who needs quick access to their tools and wants to keep their hands free while working.
