Select it for the trolley-track arrangement that specifically calls for this kit, and verify the installed rail and chain configuration before purchase. The spacer-pad reference should not be confused with a complete trolley carriage, a replacement rail or every metal track-spacer assembly shown in an operator catalog. Its purpose is a targeted service or installation requirement within the documented trolley system, rather than a universal adjustment for any commercial door opener.\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\u003eTrack assemblies specifying 71-10324\u003c\/td\u003e\n\u003ctd\u003eMatch the kit reference in the installation or service documentation.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCommercial trolley operators\u003c\/td\u003e\n\u003ctd\u003eOperator family alone does not establish fit; identify the installed track assembly.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eK75-10259 track-spacer assembly\u003c\/td\u003e\n\u003ctd\u003eA different ordering reference; do not assume the complete metal assembly is included.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eResidential opener rails\u003c\/td\u003e\n\u003ctd\u003eNo universal compatibility established.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMAXUM trolley packages\u003c\/td\u003e\n\u003ctd\u003eVerify the exact track-package specification rather than assuming every package uses the same spacer parts.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003eIdentify the Track Component Before Ordering\u003c\/h2\u003e\u003cp\u003eA trolley system includes the rails, chain, carriage, supports and spacing components. These parts can be described loosely as track hardware even though their functions and package contents differ. Photograph the installed component and locate it in the correct drawing before selecting the replacement. A pad-only requirement and a damaged metal support may need different orders.\u003c\/p\u003e\u003cp\u003eInspect the surrounding track and chain for wear, loose supports or misalignment. A replacement pad should not be used to conceal a bent rail or an incorrectly supported trolley assembly. The installer should determine why the original component wore or failed and follow the documented placement and adjustment requirements, especially if the track has been changed since the operator was installed.\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\u003e71-10324\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturer identification\u003c\/td\u003e\n\u003ctd\u003eTrolley spacer pad \/ safety field modification\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eProduct type\u003c\/td\u003e\n\u003ctd\u003eTrolley-track accessory kit\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSelection requirement\u003c\/td\u003e\n\u003ctd\u003eExact track arrangement and manufacturer kit reference\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eSeparate components\u003c\/td\u003e\n\u003ctd\u003eRail, chain and trolley carriage require their own identification\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 the operator model and complete trolley-track identification.\u003c\/li\u003e\n\u003cli\u003eConfirm the required service reference is 71-10324.\u003c\/li\u003e\n\u003cli\u003eDetermine whether the repair needs the pad kit or a broader track-spacer assembly.\u003c\/li\u003e\n\u003cli\u003eInspect chain clearance, rail alignment and supporting hardware before installation.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003ePackage Contents and Separate Requirements\u003c\/h2\u003e\u003cp\u003eThis listing identifies the 71-10324 spacer-pad kit.
