Ed -

Are you using them as amphenol covers or for some other function?

Years ago we used them as external mounting boxes for things like buzzers. On Tele Resources 32 systems we used to drill them out and mount Sonalerts (for external bells in them).

Wait! The sonalerts went in the larger size (for 50 pair cables) SE750A, maybe?
