The RAM-B-149Z-MA1 RAM Mount Marine Grade Aluminum Motorcycle Handlebar Mount with Zinc Coated U-Bolt Base consists of the 1 inch diameter RAM ball and socket system with RAM Plastic Cradle for the Magellan Blazer 12, GPS 310, 315, 320, GPSMAP 330 and 330M.
Mount Base Design:
 The RAM-B-231Z RAM Mount Powder Coated Marine Grade Aluminum Rail Base has a 1.0 inch diameter Rubber Ball designed to sit at right angles to the mounting rail. The Zinc Coated metal U-Bolt and nuts included are designed it fit on most motorcycle round handlebars, or any circular rail or pipe with diameter from 3/4 to 1.0 inch.
To mount the rail base, place the top of the base on the rail and then slide the u-bolt around the rail, into the holes in the base top. Now tighten the screws onto the u-bolt until the base is clamped firmly. If you desire, you can now slot the black rubber covers over the exposed ends of the u-bolt.
Note: If you are looking to use this mount in the elements, we suggest the RAM-B-231 Stainless Steel U-Bolt Mount.
