Common Questions & Answers
Question Answer
Question Mark Which screw do I need for XLR mount connectors in the
Patch Panels, Wall Plates, Floor Boxes and Enclosures?
We use the Recessed Flat Head Screw for almost all XLR mount connectors. *
What about Screw Length and Color? Both are personal preference except where noted for a specific screw. *
Which screw do I need for XLR mount connectors
in the Face Plates and Recessed Dish Plates?
For Face Plates and Recessed Dish Plates the holes are not tapped so we would use 3/8"
Long Recessed Flat Head Screws with the 4-40 nut and lock washer on the rear. *
Which screw do I need for the speaker modules
in the Speaker Patch Panels and Speaker Module Plates?
We would use the 1/2" pan head machine screw.
Which screw do I need to mount Module Plates in the Master
Patch Panel, Master Wall Plate, and Master Floor Box?
We would use a pan head machine screw - length is personal preference.
* Special Note about the XLR/TRS Combo Connectors The XLR/TRS combo connectors (NCJ series) are rear mounting,
self tapping connectors, for these we only use the 1/2" Pan Head.
