The JBL Vertical U-Bracket mounts to the JBL SRX912M, expanding your speaker positioning options and allowing you to tilt the speaker rather than it being in a fixed position via the top hat. This bracket attaches to either the speaker’s two top or two bottom M10 points and the suspension portion of the bracket has several M12 through-holes for using with pipe or truss clamp adapters. There are two additional M10 attachment points on this bracket for installing optional eyebolts (not included).
