Liftmaster K77-37332, COVER, RSW 12VDC
The LiftMaster K77-37332 is a replacement operator cover for RSW 12VDC swing gate operators. It shields the internal drive, battery/control area, and mechanical components from sun, rain, dust, insects, and job-site debris. A damaged or missing cover can shorten component life and may allow water or dirt into areas that were meant to stay protected.
This cover is model-specific. RSW covers can look similar to other LiftMaster swing gate covers, but the molded profile, lock area, height, and mounting layout must match the operator cabinet. Use the operator model and parts diagram to confirm fitment before replacing a cover on an older or repaired unit.

Technician Note
Use this part when the original component is damaged, missing, cracked, corroded, worn, or no longer holding the related operator assembly correctly. Because many LiftMaster and Elite parts look similar across generations, final fitment should be based on the model number and replacement parts diagram, not appearance alone.
Before Ordering
- Match the part number on the existing component or the operator parts diagram.
- Confirm the operator model, series, voltage or configuration where applicable.
- Compare mounting points, cover shape, harness plugs, and included hardware before installation.
- Do not substitute similar-looking LiftMaster parts unless the parts diagram confirms the match.
Professional Advisory
Installation should be performed with power disconnected and the gate secured. For high-voltage wiring, damaged enclosures, missing safety devices, or uncertain fitment, use a qualified gate technician.
Product Questions & Answers
Which operator does K77-37332 fit?
K77-37332 is commonly listed for LiftMaster RSW12VDC and RSW12V Series swing gate operator cover applications.
Is this the same as a CSW200 cover?
No. RSW and CSW covers use different operator housings and should not be interchanged without parts-diagram confirmation.
Why replace the operator cover?
A cracked, missing, or loose cover can expose internal components to weather and debris and can make the operator harder to secure.
Does the cover include a lock and keys?
Some references list the cover with labels, keys, and lock assembly. Confirm current kit contents if the lock hardware is needed.
Can I order by appearance only?
No. Use the RSW12VDC model number and parts diagram because similar-looking LiftMaster covers may not mount correctly.
