Elkhart 24 inch Tri-Step - Using the latest CAD technology, ETD has designed a step that not only works smoother, but also out performs anything else on the market. The strength of this step is superior to that of competitors models. This Elkhart triple step can be attached by either bolting it to the floor or welding it to the frame and it only takes one fluid motion to easily pull and extend the steps. They feature a 24 inch wide perforated tread with anti-slip safety strips along the front of the steps for addded traction. The unit is virtually bounce-out proof, requiring more than a 35degree angle to open by itself. There is a rise between the treads of approximately 7 inch each, giving you a total drop of 18.5 inch when steps are open. The bolt hole pattern will fit most of all major competitors steps for easy replacement. They are finished in a durable black E-coat. Dimensions: 27 inch overall on the brackets from side to side. The mounting bracket measures 12.25 inch from front to back and overall with the steps extended it measures 35.75 inch from front edge of step to back of mounting bracket. From top to bottom it measures 15 inch with the steps closed. 1 per package.
