The RAILBLAZA Swing Arm R-Lock is the secret weapon for anglers and gearheads who want full control over where their gear points, pivots, and locks. Whether you’re running a fish finder, GoPro, mobile device, or any RAILBLAZA accessory, this swing arm gives you 180 degrees of smooth rotation with a built-in R-Lock friction system that holds its angle—tight. Snap it into any StarPort and you can swing your screen, light, or mount out of the way when you’re casting or paddling, then bring it right back into view without touching the base. The compact design adds articulation without bulk, and the UV-stabilized polymer construction takes a beating without backing down. If your rig needs more flexibility without losing stability, this is the upgrade you didn’t know you were missing. Quick adjustability, rock-solid hold, zero wiggle. Just how it should be.
