{"product_id":"liftmaster-la500dc","title":"LiftMaster LA500DC Primary 24V DC Swing Gate Actuator Arm","description":"\u003cp\u003e\u003cstrong\u003eThe LiftMaster LA500DC is a primary 24V DC linear actuator arm for compatible LiftMaster LA500 vehicular swing-gate systems. It is the arm reference to check when replacing the primary actuator while retaining a serviceable, compatible control system. LiftMaster identifies LA500DCS separately for the secondary position in supported dual-gate installations. Select this primary arm by the complete system documentation and existing labels, and confirm the cable, bracket and control requirements before treating an arm replacement as a complete installation package.\u003c\/strong\u003e\u003c\/p\u003e\u003ch2\u003eCompatibility — Models, Versions and Exclusions\u003c\/h2\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eModel or selection point\u003c\/th\u003e\n\u003cth\u003eCompatibility requirement\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eLA500DC\u003c\/td\u003e\n\u003ctd\u003ePrimary actuator reference; confirm the complete LA500 control-system generation.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLA500DCS\u003c\/td\u003e\n\u003ctd\u003eSecondary actuator for supported dual-gate systems; not the same ordering position.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eComplete LA500 system package\u003c\/td\u003e\n\u003ctd\u003eIncludes a different scope of equipment than an arm-only service purchase.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLA400 \/ other gate systems\u003c\/td\u003e\n\u003ctd\u003eDo not substitute solely because both use 24V DC.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePreviously modified systems\u003c\/td\u003e\n\u003ctd\u003eIdentify retained controls and replacement arms individually before selecting parts.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eReplacement Arm Selection for a Complete Gate System\u003c\/h2\u003e\u003cp\u003eA matching actuator model is essential, but it does not replace an inspection of the gate itself.
