The McNaughton LCD404L Locking Cantilever TV Wall Mount has a 25-in. extended arm and is designed specifically for TVs mounted in moving vehicles. When not in use, LCD404L locks your screen securely against the wall with “SmartLock,” a patent-pending, spring-loaded pin locking mechanism with a pull-chain release. The SmartLock helps keep your TV protected from damage caused by the bumps, jiggles and motion of the road, the company says. The mount is designed to fit TVs up to 32 inches and up to 25 pounds. The full motion articulating arm swivels, tilts and extends up to 25 inches from the wall.
