Our concrete mount facilitates attachment of a junction box or entry panel to any flat concrete surface.  They are fabricated from heavy steel square tubing and hot dip galvanized for a no-maintenance install.   The concrete mount bolts to any flat concrete or masonry surface using stainless steel expansion bolts, included.  Four flat mounting feet allow easy leveling of entire unit.  New design allows pre-installed conduits coming up out of the concrete to mate with the junction box and be held securely by strut channel (see below).

Attaching to concrete is straightforward:  Using fixture as template, mark all four holes and drill with 3/8” hammer drill.  Tap expansion bolts into holes, put on washers and nuts and tighten to “set” the bolts.  Then put on additional nuts, washers, fixture, washers, and nuts, and use nuts below and above the feet to level and plumb entire fixture.  

Now offering strut channel to help secure and manage cables.  Above photo shows two RG8 sized coax cables protected with a foam sleeve and securely clamped to a length of strut channel which is attached to Concrete Mounting Fixture with our Strut Attachment Kit, available below.   Next to the coax is 7/8” hardline (center), and 1.5” conduit (right).

Strut for entry panels can be screwed to wall under box (hardware not included).  Strut is galvanized.  Clamps for individual cables can be found below. 

Note: Lengths below are slightly longer than the entry panel box widths.  This is done so that the strut comes without having the slotted holes on the back side cut in half.
