Each of the elbow chains goes twice around the elbow, and each time it goes through both of its rings. It is closed with a screwlink or a key ring. The chain should be put just above the elbow. When you do it for the first time, it is quite hard to put the elbow chains on their place, because you can use only one hand. After a couple of times it will be easier. The rings should be big and thick, with a diameter of at least with 4.5 centimeter diameter. Unfortunately, the skin of your arms can get pinched between the chain and the rings. However, this risk is much smaller when the rings are thick. They should be at least 7 mm thick. Washing your elbows in advance decreases the risk, especially when it is hot.
The elbow chain must be not too tight, to avoid circulation problems!
This is one of the chains that I use for the elbows.
I have put a color mark at the
position where I always close them, (not visible) so
that I do not have to find out the right length each time I use
them.
The smaller ring with the key ring is connected to the chest chain.
This is done with the key ring.
The bigger ring is for the back chain.
This is how everything looks on my elbow. The skin irritation is caused
by the fact that I just spent one hour in the BPBH.
