6. Top Rope Anchor – Using a Double Length Sling

In this video we review how to create a top rope anchor using a double-length sling (also known in the United States as a 4-foot sling). To create this type of top rope anchor, you’ll need the following:

1 – Double-length sling
2 – Non-locking carabiners for the bolts
1 – Locking carabiner -and- 1 non-locking carabiner
2 – non locking carabiners for the Master Point

Step 1 – Clip the two non-locking carabiners into the bolted anchor points (one carabiner for each bolt).

Step 2 – Take your double-length sling and clip it into both of the non-locking carabiners at the anchor points.

Step 3 – Pull the sling through the carabiners so you have two strands in your hand, and pull tightly in the direction of the climber to equalize.

Step 4 – Slightly above where you’re holding the sling (roughly 6 inches), pinch the two legs of the anchor together and tie a figure-eight-on-a-bight (so you end up with a tied off loop in your sling). This tied off loop is your Master Point. See above video for demonstration.

Step 5 – Clip a locking and non-locking carabiner (or two non-locking carabiners), opposite and opposed, into the Master Point.

Please remember, climbing is inherently dangerous. Climb at your own risk.
