{"product_id":"liftmaster-powerhinge3","title":"LiftMaster POWERHINGE3 Aluminum Swing-Gate Hinges — Pair, 1,000 lb","description":"\u003cp\u003e\u003cstrong\u003eThe LiftMaster POWERHINGE3 is the aluminum version of the POWERHINGE machined-block swing-gate hinge family, supplied as two hinges and rated by LiftMaster for up to 1,000 pounds per pair. It provides a material-specific choice for an appropriately designed aluminum mounting arrangement, distinct from the mixed steel\/aluminum POWERHINGE2 and all-steel POWERHINGE versions. Selection still depends on gate width, mounting geometry, frame condition and post support. A hinge pair provides pivoting support; it does not include automation equipment or correct an undersized foundation or damaged gate structure.\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\u003eAppropriate aluminum gate and support arrangement\u003c\/td\u003e\n\u003ctd\u003eHave a qualified fabricator confirm materials, attachment method and structural suitability.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePOWERHINGE2\u003c\/td\u003e\n\u003ctd\u003eMixed steel \/ aluminum version; separate material configuration.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAll-steel POWERHINGE\u003c\/td\u003e\n\u003ctd\u003eDifferent published capacity; do not transfer its rating to POWERHINGE3.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eExisting gate repair\u003c\/td\u003e\n\u003ctd\u003eCheck hinge position, frame, post and mounting surfaces before replacement.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAutomated swing gate\u003c\/td\u003e\n\u003ctd\u003eMechanical hinge fit does not establish operator or safety-device compatibility.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eA Strong Hinge Pair Needs a Sound Gate Structure\u003c\/h2\u003e\u003cp\u003eThe 1,000-pound figure is the published capacity of the pair, not a rating for each individual hinge or a guarantee for the entire gate installation. Gate width, frame condition, post support and the mounting arrangement still affect selection. A qualified installer should evaluate the complete structure before treating a hinge upgrade as the solution to a sagging or difficult-to-move gate.\u003c\/p\u003e\u003cp\u003eCorrect alignment matters as much as the hardware choice. LiftMaster’s installation instructions require the hinge shafts to share proper alignment and warn that incorrect positioning can cause poor operation and shaft failure. The gate should move correctly through its intended travel before an operator is connected or returned to service. Increasing operator force is not a repair for a binding hinge or distorted frame.\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\u003ePOWERHINGE3\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct\u003c\/td\u003e\n\u003ctd\u003eMachined-block swing-gate hinge pair\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCatalog material\u003c\/td\u003e\n\u003ctd\u003eAluminum version\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003ePublished capacity\u003c\/td\u003e\n\u003ctd\u003eUp to 1,000 lb per pair\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMounting\u003c\/td\u003e\n\u003ctd\u003eFlat mounting surfaces; verify installation drawing\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eQuantity\u003c\/td\u003e\n\u003ctd\u003eTwo hinges \/ one pair\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\u003eConfirm the gate’s weight, width, construction and intended swing path.\u003c\/li\u003e\n\u003cli\u003eHave the post, foundation, frame and existing weld areas inspected.\u003c\/li\u003e\n\u003cli\u003eCompare the mounting geometry with the current POWERHINGE installation drawing.\u003c\/li\u003e\n\u003cli\u003ePlan how the gate will be supported safely while old hinges are removed and new ones fitted.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003ePackage Contents and Separate Requirements\u003c\/h2\u003e\u003cp\u003eThe listing is for one pair of POWERHINGE3 hinges.
