As has been said about CA hinges - some people swear by them, some people swear at them. But any hinge that you have to know so many "secrets" to install correctly have too much wrong with them.

CA hinges are the only hinges ever made that have this high of a failure rate. Every other hinge system is better including monokote hinges and sewn hinges. I guess if you know all the secrets then there's nothing wrong with using them.

Add me to the group that only uses "real" hinges. I always trash CA hinges when they come in a kit.
