Do the AM and WCP chain tensioners require use of a master link?

Or can they be linked directly to the chain with a chain break tool?
The instructions say to use master links but that seems like asking for trouble.

The WCP tensioner may be installed directly into the chain without using a master link; I imagine the AM one can be as well.


We have a #25 chain tensioner ( #25 chain tensioner ) installed using the Vex chain break tool using no master links. It seems to work fine in our elevator application.
