How do you use 3/8" hardware to attach a bell box to a module
mounting rail? Could you share a picture of your typical
practice?<br><br>
The standard bell box has small, flimsy tabs to be installed on opposite
corners of the box. Only one of these tabs would line up with the
slot in the rail and the tab is too small to drill a 3/8" diameter
hole. (We have drilled a hole in the back of these boxes and used
hardware with neoprene washers, but this takes up valuable volume inside
the box and is generally not a preferred method. More importantly,
this would not allow the box to be mounted across the end of the rail, a
most advantageous position.)<br><br>
You may not be aware that the brackets depicted have holes to allow 8/32
machine screws in each of the 4 corners of the back of the bell box,
making a very secure connection. The bracket allows mounting a box
across the end of the rail opens many possibilities for conduit
routing. A lot of thought went into the design of these brackets
and it is too bad they are no longer made. Do you have any spares
you did not use?<br><br>

Why not just use 3/8\u201d hardware in the rail channel to attach the junction
box? Especially if your AHJ allows you to bury the junction box under a
module, this works and looks great. Otherwise, just extend the rail
outside the last module and attach the box there. I never saw the point
of the bracket.<br>

I actually prefer to use Unirac L-brackets for mounting J-boxes.
Sometimes I'll use the Enphase one because it comes with the Enphase whip
(and therefore I save paying $2.75 on an extra L-bracket). However, I
find the L-brackets to be sturdier and less visible.<br>

Friends:<br><br>
Enphase has changed the design of the brackets they provide to support a
j-box. This is a problem because the new ones are inferior for
these reasons:<br>
1. They do not have a hole adjacent to the back of a mounted box (to the
best of our knowledge). This hole allows for the use of the back
hub in a standard "bell" box.<br>
2. They can not be mounted offset (to see the benefits and application

3. They do not accommodate one and two gang bell boxes.<br><br>
I'd like to buy a quantity of these brackets. A jpg depiction is
attached. Does anyone have surplus?<br><br>
Does anyone else miss these enough to write Enphase and ask that they be
reinstated into the catalog?<br><br>
Thanks in advance.<br><br>
