Cab chassis and box trucks, and some of the larger step vans like the MT55, have a floor that is 16" - 44" from the ground. Installing (or replacing) a pull-out manual step is a simple and low-cost way to make it easier for you and your customers to enter your truck. The step slides in toward and under the truck body out of the way when you don't need it; you can nudge it either way with your foot.
Please measure your mounting holes center to center before ordering. The holes for the 24" step should be 22 3/4" x 4 1/2".
Also comes in a 20" length.
