The Swing Arm R-Lock is a great addition to your RAILBLAZA kit, adding the Swing Arm R-Lock lets you swing your fish finder display out of the way, move your chart plotter to a better angle, or swivel your GoPro or iPad with ease.

With R-Lock on the top, and a friction joint on the bottom, you can set your viewing angle, and then just swing it out of the way. 

(Note: N.B. Swing Arm R-Lock will not hold any device by itself, it is designed as an extension to be added to other RAILBLAZA accessories.)
