There is a Ryobi 1/4" router in there. It's made of galvanized steel sides and a 1/4" aluminum top. The fence is a beefy aluminum "L" angle with a cut out for the blade and 6" slots on the back side to move the fence (you can also see the "T" handle bolts. The top lifts up and catches at a 45* angle for adjustments and bit changes, and the whole thing is air tight so the shop vac will draw through the top cut out. Sorry for going on but I'm pretty proud of it and wanna show it off (my wife and mother-in-law were not too impressed).
