SES RPSG2BKBOX Back Box Housing for SG2
The SES-RPSG2BKBOX is a Select Engineered Systems replacement back box housing used when the original Select Gate SG2 / SG2C / SG2M systems housing, door, window, speaker area, gasket surface, or call-button wiring needs service. These parts are normally ordered to repair the existing access-control station instead of replacing the full SES telephone entry or Select Gate system.
For a technician, the important fitment details are the product family, display opening, door style, enclosure depth, gasket layout, and any included speaker, lock, lights, terminal block, or harness components. A part that looks close may still be wrong if it was built for a different line-count display or a different SES cabinet generation.
This page is written to help identify where SES-RPSG2BKBOX is commonly used and which related part numbers customers may search for. Use the compatibility list as a guide, then verify against the installed unit label, the original SES part number, and the parts diagram before replacing physical cabinet parts.

Technician Note
Check the old part, line-count opening, mounting holes, lock or speaker location, and gasket shape before ordering. These SES service parts are usually cabinet-specific, and forcing the wrong door or enclosure can create water intrusion or display alignment problems.
Before Ordering
- Match the original SES part number and product family before ordering.
- Confirm the display line count, cabinet size, door opening, gasket path, and mounting hardware.
- Inspect the existing speaker, lock, window, wiring harness, and terminal block for damage before reassembly.
- Do not assume TEC, TEC1A, TEC2, TEC4, TEC10, CAT, and Select Gate parts interchange by appearance alone.
- Disconnect power and communication wiring before servicing the entry system enclosure or door assembly.
Professional Advisory
Telephone entry and access-control enclosures protect low-voltage electronics, telephone wiring, speakers, displays, and card or keypad components from weather and physical damage. If the unit has water intrusion, damaged wiring, failed relays, unsafe grounding, or uncertain low-voltage power, have a qualified access-control technician inspect the system before returning it to service.
Product Questions & Answers
Is RPSG2BKBOX the complete SG2 entry system?
No. It is the back box housing service part for select SG2 systems. Electronics, keypad, radio, cellular modules, and front door parts are separate unless listed.
Can this be used on SG1 or SG3 units?
Do not assume it will fit. The uploaded product name points to SG2C/SG2M, so SG1 and SG3 applications should be verified by SES parts diagram.
Why is the terminal block important?
The terminal block location affects wiring service and door clearance. A mismatched housing can make wiring difficult or unsafe to reconnect.
Does this include the front door?
No. The matching SG2 front door assembly is a separate service part, commonly searched as RPSG2DOOR.
What should I check before ordering?
Check the installed SG2 model, cabinet dimensions, conduit entry, terminal block style, and condition of the front door, speaker, lock, lights, and gaskets.
