Randall May RM-ABS-ARM Articulating Arm with Right & Left Axles for ABS (Old Style)
The Randall May RM-ABS-ARM is a genuine OEM replacement articulating arm assembly for the Randall May ABS (Adjustable Back Support) system used on snare, tenor, and bass MonoPosto carriers. This assembly connects the axle and shoulder articulation points, allowing proper movement, fit, and ergonomic support for the player.
This is the older-style ABS assembly featuring the metal ABS attachment. It is designed for earlier generations of Randall May carriers but can be adapted for newer ABS systems with the addition of part RM-ARS (sold separately).
Important Compatibility Note:
This is the old-style ABS articulating arm with metal ABS attachment. To use this assembly with newer ABS carriers, it must be modified using Randall May part RM-ARS.
