We have purchased 6 of these great 36" Prepac wall cabinets in light gray. All 6 cabinets were delivered quickly, in excellent condition, and with all of the parts included. These cabinets are very easy to assemble, and all of the predrilled holes line up perfectly. These cabinets are square, once assembled, and the adjustable hinges make it so the doors are square, and close with very little gap between them. These cabinets are also light enough in weight that one person can hang them, if the doors are attached after hanging, as it makes the hanging process less awkward.These cabinets have no backs, but it does not really matter once they are filled with items, as the wall behind the cabinet gets mostly hidden anyway. The 2 center shelves are height adjustable using the included pegs. The steel hanging rail is 38" wide, so it will stick out one inch on each side of the 36" cabinet, but it can be cut with a hacksaw if necessary. There is also an extension rail included for hanging 2 cabinets side by side. These cabinets can be butted together when hung, without any gap between them. The steel hanging rail must be secured with the 3 included lag screws, into 3 wood studs. Do not try and hang these cabinets into sheetrock only. They WILL fall! These cabinets are hung on the steel rail with 3 steel hanging hooks that connect to the cabinet wood with steel bolts. The finish of these cabinets is smooth, colored laminate attached to particle board. Overall, these cabinets look very nice and function very well. The only thing we added to these cabinets is round, felt adhesive bumpers, so that the doors do not bang when being closed.Overall, these are very nice wall cabinets for the money, and I highly recommend them to anyone that is looking for some easy to assemble and hang storage space. Personally, We have been very pleased with these wall cabinets.
