How to Attach Dive Equipment Using a Bolt Snap
Bolt snaps should be firmly attached yet able to be cut off in an emergency such as a jammed clip or entanglement.
Cable ties and o-rings can be used for break-away equipment, but these break with a simple twist so should not be used for critical equipment. 30cm | 1ft of braided nylon line (cave line or utility line)
1x 316 stainless steel swivel eye bolt snap
One way to attach a bolt snap to an item of equipment (or hose) is as follows:
- Run the cave line through the eye of the bolt snap;
- Run each end of the line in opposite directions through the attachment hole of the equipment (or around the hose if that is what you are attaching to);
- Repeat steps 1 and 2 so that the line has run through the bolt snap 3 times, and around the equipment twice (in opposite directions);
- Pull the line tight until there is a 5mm | 3/16” gap between the bolt snap eye and the equipment;
- With the one end of the line sticking up through the bolt snap eye (Distance Line), wrap other end of the line 3 times around the 5 other strands of line between the bolt snap and the equipment (Wrap Line).
- Pull the Wrap Line to take out the slack.
- Pull the Distance Line to take out the slack.
- Tighten both the Wrap Line and Distance Line.
- Tie a reef knot between the two ends so that the knot sits over the steel of the bolt snap eye.
- Cut off the excess line leaving approximately 10mm | 13/32” of each end.
- Set each end alight so that it melts down to the knot, squash the melting nylon against the knot to extinguish and seal.
- Test the knot by twisting and pulling (do not be gentle).
