I have a *bunch* of Glenn Snyder Display Systems 6-foot x 2-5/8" shelves, some that I bought directly, and some that I got from a gentleman who was liquidating his late father's collection. This is the medium size, designed for O Gauge trains. It measures 6 feet long and 2-5/8" deep. Most have mounting holes already drilled on a 17" center to attach to studs in the walls, but once trains are on them you can't see any of how they are attached anyway. I also have a custom created STL file for the endcaps that you can print yourself rather than paying for them separately, which I will include with any order of five or more shelves. GSDS shelves are self-contained satin finish extruded aluminum model train display shelves with raised rails to hold your model trains in place. These shelves are hardened and engineered to support the heaviest of toy train locomotives. Made in the USA, the anodized finish will never chip or oxidize and is easy to clean. They are long, 6ft each, so the shipping can add up. I'm breaking these up into packs of ten to make shipping a little easier to deal with. They are 2lb 2oz each, so each package will be 21lb 4oz.
