It connects two 2.25\" ball bases, one at each end, and is the core linking component for most D-series helm and console installations where you need solid reach without going to a long arm.\u003c\/p\u003e\u003cp\u003eA single internal spring holds the sockets open for smooth pivoting during adjustment, then locks down firmly when tightened for a rigid, low-flex hold. At standard length, the RAMD-201U is the mid-reach option in the D-series arm family — the right choice for the majority of large-display mounting applications.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003eStandard length — the most versatile reach in the D-series arm family\u003c\/li\u003e\n\u003cli\u003eDual 2.25\" ball sockets, one at each end\u003c\/li\u003e\n\u003cli\u003eSpring-loaded sockets allow near-infinite angle adjustment\u003c\/li\u003e\n\u003cli\u003eLocks securely in position once tightened\u003c\/li\u003e\n\u003cli\u003eHeavy-duty D-series construction for large, heavy displays\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNote:\u003c\/strong\u003e This is an arm component only — ball bases and device bracket sold separately\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eCompatibility \u0026amp; System Context\u003c\/h3\u003e\u003cp\u003eThis arm is only compatible with RAM's 2.25\" ball system (D-series).

It's also the correct replacement arm when an existing D-series setup needs a new connector between two 2.25\" ball bases. The D-series system is noticeably stiffer and more rigid than 1.5\" ball setups, which matters for customers running large screens on boats that see rough water or high speeds. Always confirm the customer's bases are 2.25\" D-series before ordering — this arm will not fit 1\", 1.5\", or 2.5\" ball bases.\u003c\/p\u003e","brand":"LNS","offers":[{"title":"Default Title","offer_id":51199445008420,"sku":"170-RAMD201U","price":153.69,"currency_code":"CAD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0743\/5799\/7604\/files\/170-RAMD201U.jpg?v=1785605535","url":"https:\/\/marisolmarine.com\/products\/ram-ramd201u-standard-double-socket-arm-2-25-ball","provider":"Marisol Marine Company","version":"1.0","type":"link"}
