Nicely constructed out of hardened steel. Slides are good quality and should hold up even with repeated use. Standard 20 lb tank DOES fit, although the opening from front to back with the drawer fully open is barely large enough to accept the tank. There are no predrilled holes in the sides for attaching the drawer box to a frame, so they will need to be drilled and the steel is very hard. Anyone building an outdoor kitchen will likely have the necessary tools but be forewarned. The bolts and nuts used to attach the drawer slides to the box protrude through the wall of the box and may be problematic for sliding the box into position. The forward bolts are located right where the box will sit in a frame and may need to be repositioned.
