Tools required: Large pliers or Channel locks

1) Remove original fin strap attachment hardware.

2) Spread the new stainless steel "D-ring", hook the ends into the fin block (see below).

3) Crimp "D-ring" into fin blocks with large pliers/channel lock; option - install small tubing in the holes of the fin block to prevent wear.

4) Test the size/spring stretch (limited by internal nylon cord), it is recommended to actually wear your wet/dry boots and pull the fins on.

Attaching to fins with 'snap buckles':

Option #1:

1a) Recommended installation - drill/remove metal rivets holding buckles to fin.

1b) Crimp "D-ring" into fin block with large pliers/channel locks.

Option #2:

2a) Crimp "d-ring" through existing buckle hardware.

Alternate attachment methods:

Tie the springs to the fins with cave line.

Purchase replacement strap hardware (available at most dive shops).

Reshape the "D-ring" to accommodate almost any fin strap configuration.
