Liftmaster K41-50089, E-BOX COVER, Q009
The LiftMaster K41-50089 E-box cover, also known as Q009, is a replacement electrical box cover used on select LiftMaster and Elite commercial gate operators. The E-box cover helps protect the internal control and wiring area from direct contact, debris, and normal enclosure exposure. It is typically ordered when the original cover is cracked, missing, warped, damaged during service, or no longer fastens properly.
This is a fitment-sensitive enclosure part. Several LiftMaster/Elite gate operators use similar-looking covers, and part numbers such as Q009 and Q409 should not be mixed just because the part looks close in photos. The best way to verify this cover is to compare the original Q number, operator model, serial/generation information, and the replacement parts diagram. It is not a control board, weatherproofing repair, or full enclosure replacement.

Technician Note
Q009 and Q409 are similar catalog-style references but should be treated as separate covers unless the exact operator parts diagram confirms interchangeability.
Before Ordering
- Confirm the operator model and generation.
- Check whether the original cover is marked or listed as Q009.
- Compare mounting points and cover shape with the parts diagram.
- Do not order this item for Q409 applications without confirmation.
- Inspect the E-box for missing screws, broken mounting tabs, or water intrusion before replacing the cover.
Professional Advisory
If the E-box cover is missing due to impact damage, inspect the control board, wiring, harnesses, and enclosure seal before returning the gate operator to service. Electrical box repairs should be handled by a qualified gate technician when wiring damage is present.
