SES RPCTBKBOX Painted Back Box for CAT/TEC Units
The SES-RPCTBKBOX is a Select Engineered Systems replacement painted back box assembly used when the original CAT / TEC telephone entry 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-RPCTBKBOX 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
What does the RPCTBKBOX replace?
It replaces the painted rear back box portion used on select SES CAT/TEC telephone entry units when the existing box is damaged or no longer seals correctly.
Does this include the stainless front door?
No. This item is the back box assembly with lock latch and gasket. Front doors such as RPCTDOOR-2, RPCTDOOR-4, or RPCTDOOR-10 are separate parts.
Can I use it on any SES telephone entry unit?
No. It should be matched to the CAT/TEC cabinet style and the original SES parts diagram. TEC1A, Select Gate, and other product lines may use different housings.
Why is the gasket important?
The gasket helps seal the door-to-box area. If it is missing, flattened, or incorrectly seated, moisture can reach the speaker, display, keypad, or circuit boards.
What should be checked before replacing a back box?
Check the wall opening, conduit location, hinge/door alignment, latch position, gasket path, and condition of any wiring passing through the enclosure.
