Scanstrut RL-505-ARM-NEW Rok-Lok Adjustable Rail Mount

Scanstrut Rok-Lok Adjustable Rail Mount - Lowrance HDS-7 & AMPS Universal (RL-505-ARM-NEW)

The Scanstrut RL-505-ARM-NEW is a heavy-duty, fully adjustable Rok-Lok Series Rail Mount System with Extended Arm engineered to provide an extended reach and multi-position mounting solution for 7-inch displays—specifically the Lowrance HDS-7 and HDS-7m series—as well as any marine electronics using the standard AMPS hole pattern. It attaches securely to marine guard rails, pushpit tubing, and helm pedestal rails measuring 25 mm to 33.7 mm (1" to 1.33") in outer diameter.

Equipped with an extended adjustable arm body (RL-ARM base) paired with the RL-505 top plate, this system provides full multi-axis rotation and tilt control. Scanstrut's metal-on-metal Rok-Lok locking mechanism ensures that once set, the display remains locked in place without gradual slipping or sagging, even under heavy engine vibration, high wave impact, and severe sea conditions.
