Install a Junction-Box-Style Fixture in a 90° Inside Corner

This ASA mount creates a round fixture face within a square inside corner. It accepts the factory crossbar supplied with compatible lights, floodlight cameras, and other fixtures designed for a nominal 4-inch junction-box interface.

🌟 What This Mount Does

  • Inside-corner placement: Creates a forward-facing round mounting surface where two inward-facing wall surfaces meet.
  • Broad fixture compatibility: Accepts fixtures that use a crossbar and standard 4-inch junction-box mounting patterns.
  • Fixture support: Designed to support a compatible junction-box-mounted fixture when securely installed with appropriate fasteners.

📐 Fit & Dimensions

  • Round fixture face: 127 mm (5 in) diameter
  • Depth: 65 mm (2.6 in)
  • Crossbar mounting: Four bosses at 3.5-inch spacing and four bosses at 2.75-inch spacing; most installations use two opposing holes.
  • Corner geometry: Square 90° inside corners only

🔩 Mounting & Structure

  • Fastens directly to the building through the rear mounting holes.
  • Use the fixture's supplied crossbar and hardware. Two included thread-forming screws retain the crossbar in the selected boss pair.
  • Wall screws and anchors are not included; choose fasteners appropriate for the wall material and installed load.

Intended for standard junction-box-mounted fixtures only. No load rating is provided.

🔌 Wiring & Moisture Management

  • Two threaded 1/2-inch NPT openings accept standard electrical conduit adapters.
  • Two closure plugs are included for unused openings; conduit fittings are not included.
  • No gasket is included. A properly fitted fixture gasket and correctly installed conduit fittings provide reasonable weather protection.
  • An integrated drain opening allows incidental moisture to weep out. The mount is not represented as a watertight enclosure.

📦 In The Box

  • 1 inside-corner mount in the selected color
  • 2 × #8 × 3/4-inch thread-forming screws for the fixture crossbar
  • 2 closure plugs

Fixture, fixture crossbar and hardware, wall fasteners, anchors, gasket, conduit fittings, conduit, and wiring are not included.

🛠️ Installation Notes

  1. Turn off power and verify the circuit is de-energized.
  2. Fasten the mount securely to both faces of the 90° inside corner using appropriate customer-supplied wall fasteners.
  3. Install the required conduit fitting and close every unused NPT opening.
  4. Attach the fixture's crossbar to the matching boss pair with the included screws, complete the wiring, and install the fixture according to its instructions.
