description: long type 302 SS extension spring 11" length, 1/2 inch OD,. .062 " wire diameter.
unit price: 4.99
This is the info from the invoice. I bought enough to do 10 pr. fins. I have done my own, started on my son's but only have one of his 2 fins as the other fin is in Seattle.
For the strap, You bend down 1 1/2 round turns of spring and use a small brass grommet . Grommet kits are available at any hardware store. You cannot use the large grommet. You put the grommet on and use the hammer as usual to affix the grommet. Don't try to really smash the grommet too flat as I have found you can break the spring in the grommet and have to cut the grommet off and have to start with 2 new loops. This may not be too much of a problem , but if you lose too much spring it can get too tight on your foot.
I have placed vinyl hose on the spring as recommendedby others, but this makes it too stiff over the achilles tendon, and I am thinking of cutting the vinyl tube off as it doesn't help at all and increases likelihood for discomfort . The spring seems to be comfy on its own without need for a plastic cover.
Once you have affixed one side, and screwed it to the fin,. put the fin on your foot with the bootie and measure how much of the spring you'll need to keep. Using a strong wire cutter, you snip off the extra spring amount, and bend down the last 1 1/2 or 2 coil segments so you can attach the grommet. Q.E.D.
For other fins (not force fins,), I found some neat SS hurricane shutter mounting hardware thet had a large flanged flat 1/4 inch bolt in SS and Brass inserts for the boards to go over windows. These can be mounted through rubber of any standard fin with a drilled hole and will mount the springs and look spiffy.
