I really like this product, it is small and easy to use and with a little work the keystone can be removed and the housing can be reused

      Comments about Signamax Inc Signamax Keystone Industrial Din-Rail Mounting Module, 2 Side Lids:

      Preface: I may not have used the proper jack with this housing.

      Upon receipt of the housings I snapped a Hubbell Excellerator jack into one of them to test before taking it into the field. The fit was a bit tight but the real surprise was that its design prevents access to the wiring posts and that the jack cannot be removed without destroying the housing. Scratch one housing.
