{"product_id":"liftmaster-k45-50676","title":"LiftMaster K45-50676 Clutch-Cover Thumb Screw \/ Star Knob — CSW200","description":"\u003cp\u003e\u003cstrong\u003eThe LiftMaster K45-50676 is the star-knob or thumb-screw service reference used in the documented CSW200 clutch-cover arrangement. It secures the intended cover connection and must be matched to the installed operator generation and mating hardware. This small component is different from the clutch-release handle, complete cover and internal clutch assembly. Select it after checking the receiving threads and cover alignment, especially when the original knob has been lost or damaged; a replacement screw cannot restore a stripped mounting point or straighten a distorted cover.\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\u003eDocumented CSW200 clutch-cover mounting\u003c\/td\u003e\n\u003ctd\u003eMatch the knob to the actual cover and attachment point.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOther swing-gate families\u003c\/td\u003e\n\u003ctd\u003eVerify their own service diagram before assuming fit.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eRelease handle or clutch assembly\u003c\/td\u003e\n\u003ctd\u003eDifferent components; this knob is not a complete release repair.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eGeneric screws with similar appearance\u003c\/td\u003e\n\u003ctd\u003eThread engagement, length and seating must match the approved part.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eStripped or distorted mounting point\u003c\/td\u003e\n\u003ctd\u003eRepair the receiving component separately.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eInspect the Cover Attachment Before Replacing the Knob\u003c\/h2\u003e\u003cp\u003eA missing or loose knob should prompt inspection of the cover, receiving threads and surrounding mounting features. A screw that repeatedly loosens may indicate damaged threads or a cover that does not seat correctly. Do not force a replacement into a misaligned connection, and do not use a longer screw merely because it catches the remaining threads.\u003c\/p\u003e\u003cp\u003eThe manufacturer identifies the star knob separately from the cover and operating linkage. Preserve those distinct functions during the repair. The technician should confirm that the cover fits without interfering with the mechanism and that normal service access remains possible. Follow the specified attachment method; a small fastener is still part of restoring the operator’s intended enclosure and guarding arrangement.\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\u003ePart number\u003c\/td\u003e\n\u003ctd\u003eK45-50676\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturer description\u003c\/td\u003e\n\u003ctd\u003eStar knob\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSource description\u003c\/td\u003e\n\u003ctd\u003eClutch-cover thumb screw\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eDocumented family\u003c\/td\u003e\n\u003ctd\u003eCSW200 \/ legacy CSW200UL arrangement\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSeparate components\u003c\/td\u003e\n\u003ctd\u003eCover, release handle and clutch assembly\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSelection basis\u003c\/td\u003e\n\u003ctd\u003eExact service reference and receiving connection\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 full operator and clutch-cover arrangement.\u003c\/li\u003e\n\u003cli\u003eMatch K45-50676 in the applicable parts drawing.\u003c\/li\u003e\n\u003cli\u003eInspect the receiving threads and cover seating for damage.\u003c\/li\u003e\n\u003cli\u003eConfirm the supplied quantity and any additional enclosure repair parts.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003ePackage Contents and Separate Requirements\u003c\/h2\u003e\u003cp\u003eThis offer identifies the K45-50676 star-knob \/ thumb-screw service item.
