About the Mackie PA-A2 Eyebolt Kit for SRM V-CLASS, DRM Series, SRM550, SRM650 & SRM750
The Mackie PA-A2 Eyebolt Kit is a certified rigging hardware package engineered for the safe overhead suspension of specific high-power Mackie loudspeaker models, including the SRM V-CLASS, DRM Series, SRM550, SRM650, and SRM750. This kit provides the critical, load-rated components required to convert these heavy-duty powered speakers into elements suitable for flown arrays in permanent installations or temporary rigging for concerts and events. The kit includes high-tensile, forged steel eyebolts that thread directly into the reinforced M20 rigging points built into the speaker cabinets. These eyebolts serve as the primary attachment points for professional flying hardware such as steel shackles, wire rope assemblies, or chains, which are then connected to a structurally certified overhead truss or ceiling support, allowing for optimal acoustic placement and significant space savings on the stage floor.
Safety and compliance with stringent entertainment rigging standards are the cornerstone of this kit's design. Each eyebolt is manufactured to exacting specifications, with a clearly defined working load limit (WLL) and minimum breaking strength that incorporates a substantial safety factor as per guidelines like ANSI E1.2. The threading is precision-matched to ensure full engagement with the speaker's mounting inserts without cross-threading. The kit typically includes secondary locking hardware, such as lock washers or nylon-insert locknuts, to mechanically secure the eyebolts and prevent them from loosening due to speaker vibration or dynamic loads during use. Proper installation requires that each eyebolt be torqued to the manufacturer's specified value using a calibrated torque wrench, a non-negotiable step to guarantee the connection's integrity under load.
Utilization of the PA-A2 kit demands expertise from a qualified rigger who can perform load calculations, inspect all supporting structures, and ensure the entire suspension system complies with local safety regulations. The kit allows for angular adjustment of the speaker via the secondary rigging hardware, enabling precise aiming of the flown cabinets for the desired coverage pattern. By supplying manufacturer-approved, tested rigging hardware, the Mackie PA-A2 Eyebolt Kit ensures that production companies and installers can safely deploy these powerful speaker models in flown configurations, maintaining the highest standards of safety while achieving the acoustic and logistical benefits of elevated speaker deployment in large venues.
