The LiftMaster LA500UL dual swing gate operator package is designed for residential and light-commercial vehicular swing gates requiring two powered gate leaves. This configuration combines the LA500PKGUL primary operator package with the LA500DCS secondary 24VDC actuator to create a matched LA500 dual-gate system.
LiftMaster identifies LA500PKGUL as the primary single-arm package. The LA500DCS is the secondary actuator specifically used for the second leaf of a compatible LA500 dual swing gate. This distinction is important when comparing complete packages, primary actuator arms, secondary arms, and replacement control equipment.
The LA500 platform uses 24VDC linear actuators to open and close heavier swing gates while providing smooth start/stop operation, battery backup, onboard diagnostics, Security+ 2.0 radio technology, and integration with compatible LiftMaster access-control and myQ equipment.
For a dual swing installation, the primary and secondary gate leaves are coordinated through the LA500 control system. Proper gate geometry, physical stops, actuator mounting, wiring, sequencing, and entrapment protection are required for reliable operation.
Package-content note: Bundle contents can change or be packaged separately. Confirm the current Gate Openers Unlimited package contents before ordering if a specific bracket, cable, battery, photo eye, reflector, hardware kit, or other accessory is required.
The LA500 should not be selected by maximum gate weight alone. LiftMaster's published capacity decreases as gate-leaf length increases. Each leaf of a dual gate should be evaluated separately.
| Gate Leaf Length | Published Maximum Weight |
|---|---|
| 8 ft | Approximately 1,600 lb |
| 12 ft | Approximately 1,200 lb |
| 16 ft | Approximately 800 lb |
| 18 ft | Approximately 600 lb |
Actual suitability also depends on wind loading, gate construction, hinge condition, gate balance, mounting geometry, frequency of use, accessory load, and site conditions.

LA500PKGUL, LA500DC, and LA500DCS are related but are not the same item. LA500PKGUL is the primary operator package, LA500DC is the primary actuator, and LA500DCS is the secondary actuator intended for the second gate leaf in a dual LA500 installation.
Do not substitute LA400, LA400DC, LA400DCS, LA412, or LA412DCS actuators for LA500 actuators simply because the units appear similar. Motor, actuator, control, mounting, and system requirements can differ.
Related numbers identify components or earlier LA500 family references and should not automatically be treated as interchangeable complete packages.
The LA500UL is intended for vehicular gates only. A complete installation requires properly located monitored entrapment protection for all applicable entrapment zones. The included or supplied photo eye does not automatically satisfy every safety requirement for every gate layout.
Never bypass monitored photo eyes, edge sensors, obstruction sensing, emergency access equipment, or other required safety circuits to make an operator run. A qualified gate technician should evaluate the completed gate for UL 325 entrapment protection requirements and local code compliance.
On a dual LA500 installation, both gate leaves should swing freely by hand before the actuators are installed. Dragging hinges, poorly aligned gates, incorrect bracket setback, missing physical stops, excessive wind loading, or mismatched gate leaves can cause obstruction faults, poor synchronization, shortened actuator life, or damage to the operator.
LA500 installation involves actuator geometry, gate limits, force settings, low-voltage control wiring, battery charging, safety inputs, and line-voltage power to the control system. Incorrect installation can damage the equipment or create an unsafe gate system.
High-voltage wiring, internal electrical troubleshooting, battery charging faults, transformer failures, safety-circuit problems, and final entrapment-protection testing should be handled by a qualified gate or access-control technician.
No. LiftMaster identifies LA500PKGUL as the primary single-arm package. A typical dual LA500 configuration adds the LA500DCS secondary actuator for the second gate leaf.
LA500DC is the primary 24VDC actuator associated with the LA500PKGUL system. LA500DCS is the secondary 24VDC actuator designed for the second leaf of a compatible dual LA500 swing gate.
No. The maximum length and maximum weight are not simultaneous ratings. The published chart is approximately 1,600 lb at 8 ft, 1,200 lb at 12 ft, 800 lb at 16 ft, and 600 lb at 18 ft per gate leaf.
Yes. The standard LA500PKGUL control system uses battery backup and is commonly supplied with two 7Ah batteries. Confirm the current bundle contents before ordering if batteries are a critical package requirement.
Not necessarily. The required number and location of monitored entrapment protection devices depends on the gate layout and identified entrapment zones. Additional monitored photo eyes or edge sensors may be required.
No. LA400DCS and LA412DCS should not be substituted for LA500DCS. Confirm the actuator family and existing control system before ordering replacement or additional arms.
Yes, the LA500 platform is solar ready when configured with the correct LiftMaster solar equipment, battery capacity, panel sizing, and accessory load calculations. Solar design should be verified for the actual site.
Verify each gate leaf's length and weight, hinge condition, physical stops, actuator mounting geometry, power source, control equipment, accessory load, required entrapment protection, and the exact contents of the dual operator bundle.
