The cables are made from high-quality "dipped" rubber. Dipped rubber cables offer several advantages
over steel cables, notably that they are lighter, more flexible,
and won't pinch like steel springs.
We offer only cables made with dipped rubber tubing,
while many other models offered use extruded rubber.
The difference?
Extruded rubber tubing is much cheaper,
and is made by forcing rubber through a die, resulting
in one thick layer of rubber, similar to how a rubber band is made.
If there are any defects in this layer, the Cable will fail
prematurely. Dipped rubber is made similar to how a candle is made,
where the tubing is dipped several times in liquid rubber, resulting in several layers.
In fact, if you look at the end of our Cables under magnification,
you will see rings similar to the trunk of a tree. With dipped rubber,
if one layer is weak, the other layers will
compensate for it and the Cable will not fail.
We know of several people who
have had their Cables for 15 to 20 years, and although some of the layers of the Cable
are shredded, they continue to use the Cable, and it does not break.
If you use the cables regularly, for the purpose of safety and consistent
resistance strength, we recommend that you replace them at least once a year.
You can extend the life of your cables by keeping them in a cool, dry place out of direct sunlight or
other heat, and wiping them down regularly. We have heard from customers who regularly wipe down their
cables with Armor-All protectant to maintain the suppleness of the rubber and extend the overall
life of the cables.
