Stop leaving your Holley screen in a glove box or rolling around on the floor. This mount lets you place the screen right on the column. Comes with a black 4" hose clamp for a more professional looking install. Built in sun visor to keep the screen readable and tipped slightly forward to help with glare. The 3.5 inch screen fits snuggly in the holder and will not fall out or rattle. Made from durable ABS plastic to survive in the heat and cold.
