{"product_id":"liftmaster-q082","title":"LiftMaster Q082 \/ K13-50140 Limit Nut — Legacy HCT","description":"\u003cp\u003e\u003cstrong\u003eThe LiftMaster Q082 supplier SKU identifies the K13-50140 limit-nut service item for documented legacy HCT overhead-gate operator arrangements. The HCT parts list names it separately from the limit-switch bolt, electrical switch and complete trolley. Match the installed limit mechanism and exact repair drawing before ordering. A travel nut helps establish the specified switch-actuation position; it is not a safety sensor or a substitute for diagnosing a gate that stops inconsistently because of wiring, switch wear or another mechanical fault.\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\u003eLegacy HCT drawings naming Q082\u003c\/td\u003e\n\u003ctd\u003eMatch installed travel-limit arrangement.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eK13-50140 mapping\u003c\/td\u003e\n\u003ctd\u003ePreserve both identifiers when confirming the order.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eQ081 bolt\u003c\/td\u003e\n\u003ctd\u003eSeparate component.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eQ032 legacy slide-gate limit nut\u003c\/td\u003e\n\u003ctd\u003eDifferent service reference.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eLater HCT generations\u003c\/td\u003e\n\u003ctd\u003eRequire their own exact repair list.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eCheck the Nut, Retention and Limit Actuation\u003c\/h2\u003e\u003cp\u003eRecord the full HCT model and photograph the limit mechanism before disturbing adjustment. Have the technician identify wear in the nut, mating bolt, retention and switch-actuation surfaces. A nut that shifts or fails to actuate a switch can be only part of a larger problem. Do not choose a generic nut solely because it appears to fit the thread or reaches the same position.\u003c\/p\u003e\u003cp\u003eRestore the documented retention and adjustment arrangement rather than adding improvised locking hardware. A correct replacement still needs the model-specific travel-setting procedure. After service, verify both endpoints and the operator’s response throughout the complete movement, then test reversal and required entrapment protection separately. A continuity check at the switch or a visible nut position alone does not demonstrate safe operation of the whole gate.\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\u003eSupplier SKU\u003c\/td\u003e\n\u003ctd\u003eQ082\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturer reference\u003c\/td\u003e\n\u003ctd\u003eK13-50140\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct\u003c\/td\u003e\n\u003ctd\u003eLimit nut\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDocumented platform\u003c\/td\u003e\n\u003ctd\u003eLegacy HCT\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSeparate component\u003c\/td\u003e\n\u003ctd\u003eQ081 limit-switch bolt\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eQuantity and thread\u003c\/td\u003e\n\u003ctd\u003eConfirm current package and exact mechanism\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\u003eRecord exact HCT model and limit arrangement.\u003c\/li\u003e\n\u003cli\u003eMatch Q082 to K13-50140.\u003c\/li\u003e\n\u003cli\u003eInspect bolt, retention and switch actuation.\u003c\/li\u003e\n\u003cli\u003eConfirm package quantity and required post-repair travel setup.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003ePackage Contents and Separate Requirements\u003c\/h2\u003e\u003cp\u003eThis offer identifies the Q082 \/K13-50140 limit-nut service item.
