Miller Edge JB-03-FLEX Junction Box Conduit Kit for Invis-Guard-2 Photo Eyes
The Miller Edge JB-03-FLEX is used to help route and protect low-voltage wiring on select Invisi-Guard-2 photo eye installations. In the field, photo eye wiring is often exposed near posts, guides, gate frames, or door tracks. A junction box and flexible conduit kit helps keep the wiring cleaner, easier to service, and less exposed to abrasion or outdoor damage.
This is an installation accessory, not a complete safety device. It does not include a photo eye emitter and receiver unless a specific listing says so. Because conduit routing can affect both service access and sensor alignment, the installer should plan the box location before mounting the eyes.

Technician Note
Do not place the junction box where it blocks the photo eye beam, gets hit by the gate, or makes the sensor impossible to align. Also avoid stuffing low-voltage splices into an operator cabinet in a way that makes future troubleshooting difficult.
Before Ordering
- Confirm the photo eye model and whether the kit is being used with IG2 or another Miller Edge photo optic system.
- Verify conduit size, box placement, and wire path before mounting hardware.
- Make sure the box location stays clear of gate travel, door guides, vehicles, and service access panels.
- Check local electrical and low-voltage requirements for the installation.
- After wiring, test the photo eye and confirm the operator stops or reverses as required.
Professional Advisory
Photo eyes are part of the entrapment protection system. Do not bypass or defeat photo-eye inputs to make an operator run. If the gate or door will not close after service, have the alignment, wiring, monitored/non-monitored setting, and operator safety inputs checked by a qualified technician.
Product Questions and Answers
Is JB-03-FLEX a photo eye kit?
No. JB-03-FLEX is a junction box and flexible conduit accessory kit. The photo eye emitter and receiver are separate unless the listing specifically includes them.
What is the main use of this conduit kit?
It is used to help protect and route low-voltage photo eye wiring on compatible gate and motorized door installations.
Can JB-03-FLEX be used with Invisi-Guard-2 photo eyes?
Yes, it is commonly associated with Invisi-Guard-2 / IG2 photo eye installations, but the existing sensor model and mounting layout should be verified.
Will this kit fix a photo eye fault?
No. A conduit kit protects and organizes wiring. Faults still require checking power, alignment, wiring continuity, batteries, and the operator safety input.
Can I use this with a Rebel photo eye?
JB-03-FLEX is commonly searched with Rebel photo eye conduit applications, but do not assume fitment. Verify the exact photo eye body, conduit connection, and mounting requirements before ordering.
