The following hold measurements are from end to end. The Tall measurement and the Standing Off The Wall measurement have been averaged. The rails range from 1" to 1-1/2" standing off of the wall. The Tall measurement also ranges from 1" to 2".
9" long x 2" tall x 1-1/2" standing off the wall
11-1/2" long x 2" tall x 1-1/2" standing off the wall
13" long x 2" tall x 1-1/2" standing off the wall
15" long x 2" tall x 1-1/2" standing off the wall
16-1/2" long x 2" tall x 1-1/2" standing off the wall
