{"product_id":"liftmaster-mg1300","title":"LiftMaster MG1300 Magnetic Gate Lock — 1,300-Pound Rated Holding Force","description":"\u003cp\u003e\u003cstrong\u003eThe LiftMaster MG1300 is a magnetic gate lock offered with a rated holding force of 1,300 pounds. It is designed to be integrated with a suitable gate structure, power supply and release-control arrangement. The supplier identifies an included transformer, and the manufacturer instructions describe a supplied 12V DC power arrangement with a separate 24V DC option. Treat the holding-force figure as a lock rating, not a gate-weight capacity or a guarantee of the strength of the complete installation.\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\u003eGate and post structure\u003c\/td\u003e\n\u003ctd\u003eRequires suitable mounting surfaces and proper magnet\/armature alignment.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGate operator lock control\u003c\/td\u003e\n\u003ctd\u003eConfirm a compatible release function and electrical arrangement; brand alone does not prove fit.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e12V versus 24V DC\u003c\/td\u003e\n\u003ctd\u003eSelect the documented wiring and supply for the intended configuration.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\n\u003ca href=\"https:\/\/garage-doorparts.com\/products\/liftmaster-automatic-garage-door-lock\"\u003e841LM\u003c\/a\u003e garage-door lock\u003c\/td\u003e\n\u003ctd\u003eA different powered deadbolt product for specified garage-door systems, not an interchangeable magnetic gate lock.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eHolding Force Depends on the Complete Installation\u003c\/h2\u003e\u003cp\u003eA magnetic lock needs correct contact between the magnet and armature. The manufacturer warns that contamination or surface defects can interfere with that contact. Have the installer assess the mounting position, gate movement and support structure before selecting this lock. A loose post or misaligned gate cannot be corrected by choosing a larger holding-force number.\u003c\/p\u003e\u003cp\u003eThe lock must release in coordination with the gate’s authorized movement. Plan the control interface and power arrangement before installation rather than assuming an operator’s accessory output can supply or switch the lock directly. Where an entry has required emergency release or exit provisions, have the qualified installer verify those requirements for the actual site; a product description is not a complete access-system design.\u003c\/p\u003e\u003ch2\u003eSpecifications and Product Identification\u003c\/h2\u003e\u003ctable\u003e\n\u003cthead\u003e\u003ctr\u003e\n\u003cth\u003eSpecification\u003c\/th\u003e\n\u003cth\u003eDetails\u003c\/th\u003e\n\u003c\/tr\u003e\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003eModel\u003c\/td\u003e\n\u003ctd\u003eMG1300\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct type\u003c\/td\u003e\n\u003ctd\u003eElectromagnetic gate lock\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSupplier-rated holding force\u003c\/td\u003e\n\u003ctd\u003e1,300 lb\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSupported lock supply configurations\u003c\/td\u003e\n\u003ctd\u003e12V DC or 24V DC, wired according to the manufacturer instructions\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSupplied power arrangement\u003c\/td\u003e\n\u003ctd\u003e12V DC transformer identified in manufacturer inventory\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e24V DC supply\u003c\/td\u003e\n\u003ctd\u003eSeparate; not provided in the manufacturer inventory\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eHousing\u003c\/td\u003e\n\u003ctd\u003eStainless steel, per manufacturer sheet\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eBefore Ordering\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eIdentify the operator model and intended lock-release control.\u003c\/li\u003e\n\u003cli\u003eConfirm 12V or 24V DC operation and the separate supply requirements.\u003c\/li\u003e\n\u003cli\u003eInspect the gate and post for suitable mounting and alignment.\u003c\/li\u003e\n\u003cli\u003eConfirm the current carton contents and any site-specific brackets or electrical materials.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003ePackage Contents and Separate Requirements\u003c\/h2\u003e\u003cp\u003eThe manufacturer sheet identifies the lock, armature components, mounting plates\/junction-box parts and a 12V DC transformer.
