{"product_id":"liftmaster-ma022","title":"LiftMaster MA022 Barrier Arm Bolt — Documented Mega Arm Mounting Hardware","description":"\u003cp\u003e\u003cstrong\u003eThe LiftMaster MA022 is the arm-bolt service reference identified in the documented Mega Arm barrier assembly. It belongs to the specified arm attachment and must be distinguished from the nylon arm nuts, arm bracket and separate shear pin. The manufacturer diagram identifies two arm bolts in the assembly, but that installed quantity does not by itself establish the quantity sold in this supplier offer. Confirm the current package and match the approved mounting hardware before ordering, especially when repairing a barrier after a vehicle impact.\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 Mega Arm attachment\u003c\/td\u003e\n\u003ctd\u003eUse the bolt reference specified for the actual arm mounting.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMA010 bracket\u003c\/td\u003e\n\u003ctd\u003eSeparate mounting component; verify condition before installing new bolts.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMA021 nylon arm nuts\u003c\/td\u003e\n\u003ctd\u003eSeparate specified hardware; do not substitute a generic nut without approval.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eMA013 shear pin\u003c\/td\u003e\n\u003ctd\u003eDifferent component and function, not the same as an arm bolt.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eOther barrier-arm arrangements\u003c\/td\u003e\n\u003ctd\u003eVerify the exact drawing and hardware requirements before assuming fit.\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\u003ch2\u003ePreserve the Specified Arm Attachment After a Repair\u003c\/h2\u003e\u003cp\u003eInspect the bracket, arm mounting holes, nuts and surrounding connection whenever an attachment bolt is missing, loose or damaged.
