Use these carabiners to help hang batting cages, nets and more. Anything that needs to be taken down when not in use, for reasons like weather protection and use of the space for other purposes, will benefit from a pack of these. We sell them in packs of 50 and recommend that you hang them every 1.5-2 feet. These are perfect for attaching your net to a frame, poles, pulley, or cable. A 35ft net= 1 pack, 55ft net=2 packs, 70ft= 2-3 packs
