Quad Anchors a.k.a. 2 Piece Anchors
Like most aspects of climbing, there are many ways to build a good quad anchor. This kit uses a 8mmX240cm sling, 2 non lockers and a HMS Strike Screw. I like having a little more flexibility in building my 2 and 3 piece anchors, so I use a 240cm sling instead of a 180cm sling.
You may need additional equipment. This is not a recommendation! I am sharing my opinions, which might be wrong. Remember, buying equipment does not equal knowing how to use it. These kits are NOT designed for industrial or professional rescue work.
