Marantec 122946, Housing Set for Synergy 200 models
The Marantec 122946 housing set is the exterior enclosure used on the Synergy 200 series opener head. The housing protects the internal operator components and gives the opener a finished, serviceable appearance. It is often replaced after physical damage, yellowing, cracking, or removal damage during repair. While a housing set may seem like a simple cover, Marantec opener bodies use model-specific shapes and mounting points, so correct identification is important. The 122946 should be used only where the operator parts diagram lists this part. It is generally tied to Synergy 260, 270, and 280 applications and should not be confused with Synergy Solo housing part 122941 or Synergy 360/370/380 housing references such as 122947.

Technician Note
Match this Marantec part by the model label, original part number, rail type, frequency, or parts diagram before ordering. Marantec used similar-looking parts across several generations, and small differences in receiver frequency, housing shape, rail style, or sensor hardware can prevent a proper repair.
Before Ordering Checklist
- Confirm the Marantec model number on the opener head or parts diagram.
- Compare the original part number to the number shown on this product page.
- For rail parts, confirm chain versus belt rail and standard versus heavy-duty rail.
- For receivers, confirm the operating frequency and remote family before ordering.
- For photo eye parts, repair the safety system properly and never bypass required sensors.
Professional Advisory
Garage door openers can involve spring-loaded doors, moving drive systems, low-voltage safety circuits, and internal electrical parts. If the repair involves power diagnosis, failed safety devices, a door that will not balance, or an opener that moves unpredictably, have a qualified garage door technician inspect the system before returning it to service.
