This Low Profile model is designed with all the same features and technology you have come to expect from the Standard Solo post model 10xx. The advantage of the Low Profile model is that it is at the lowest height possible above the deck or mounted atop a box, with the same travel stroke, strength, and swiveling action. Requirements to mount are a 5.5-inch round hole and 5.5 inches of space below the deck or inside the box. The height above is 11 inches.
