This is an industrial walkway with railings that fold down. Any gamers that live in an apartment know it's hard to keep any amount of terrain around without it getting crushed or pissing off your room mates. With the railings folded down it is 1cm high. This piece of terrain is designed for use with any 28mm game you see fit. When you receive your walkway, the railings may not be centered as they are in the video and pictures. EASY FIX! Just fold your railings all the way out and you will be able to gently guide them through the supports to their centered position. One of the images shows a miniature for scale but it is not included with this model.
