It is part of a system that allows for the creation of platforms of various sizes and shapes, compatible with PECO TT:120 track. The platform edging considers sleeper height for accurate scale representation. The surface sheets can also be used for scratch-building structures. Assembly requires a craft knife, files, and liquid poly cement. Recommended for use with LK-12103, LK-12104 platform edging, and LK-12105, LK-12106 platform ramp edges.
