This innovative step does more than fold up. The step flips up and then slides under the floor so when it is closed it is nicely hidden and compact, hanging only 3-3/4" below the floor.
You can even mount a faceplate to it if you wish so that the front looks the same color as your trailer when the step is retracted. The faceplate is not included so you can fabricate from aluminum or steel as needed.
Finished in a durable black enamel (expect minor imperfections in the finish due to bulk handling).
