LiftMaster K10-30678 Lock Bar for SL575GL and SL585GL Slide Gate Operators
The LiftMaster K10-30678 lock bar is a structural replacement part used in the enclosure and cover locking area on select heavy-duty LiftMaster industrial slide gate operators. This is not an electronic lock and it is not a gate lock for securing the moving gate leaf. It is a mechanical lock bar used with the operator cabinet or cover hardware so the service cover can seat and secure correctly. A bent, missing, or worn lock bar can leave the operator cover loose, make the cabinet harder to close, or allow vibration around the enclosure during normal gate travel. On outdoor slide gate systems, the cabinet hardware matters because it helps protect the drive components, controls, and internal wiring from weather, vibration, and jobsite damage. Fitment should be matched to the operator model and parts diagram because similar SL-series cabinet parts can look close but use different bends, hole spacing, or cover geometry.

Before Ordering Checklist
- Match the operator model to SL575GL or SL585GL before ordering.

- Inspect the cover, latch, hinges, and enclosure for damage that may have caused the lock bar to fail.
- Confirm whether related cabinet hardware is also needed.
Professional Advisory
Gate operators can contain moving mechanical parts, stored force, battery circuits, and high-voltage wiring depending on the model. Do not bypass safety devices or operate the gate with exposed, loose, or damaged components. If the operator has unsafe movement, burned wiring, power problems, or missing safety protection, have the system inspected by a qualified gate technician.
Product Questions and Answers
Is K10-30678 an electric gate lock?
No. K10-30678 is a lock bar for the operator enclosure or cover area, not an electric lock for locking the moving gate.
Which operators commonly use this lock bar?
It is commonly listed for LiftMaster SL575GL and SL585GL industrial slide gate operators.
Can I use this on an SL595 operator?
Do not assume it fits an SL595. SL-series cabinet parts vary, so use the exact parts diagram for the operator.
Why would this lock bar need replacement?
It may need replacement if it is bent, missing, rusted, or no longer lets the cover latch and seat properly.
Should the cover hardware be inspected too?
Yes. A damaged hinge, latch, cover, or cabinet can make a new lock bar difficult to align.
