Screw links are the perfect solution for situations where a more permanent attachment is needed, or when speed is secondary. They work great on the end of your ascenders, at the tops of towers, distributed slings, and chest harnesses.

The Delta Quick Link is designed to take loads across more than one axis, which ordinary carabiners aren't rated for. Excellent for attaching your chest and sit harness. The Delta is constructed out of 8mm stainless steel and has a working load limit of 1,000 lbs  Max load rated at 4,400 lbs. CE certified.
