The description says "Features front, rear, and top threaded rack rail." Actually, there is NO rear rack rail. Other than that, great product!!! It seems a little delicate...like if I drop it more than once full of gear, it will break....maybe I'm paranoid. BUT, it is well-built, and it comes with rack screws!

We all know gator makes quality stuff. This will not let you down. 4 spaces on the bottom 10 on the top. The way I set it up is my peavey 14 mixer on top with the additional rack mount kit (the problem with this is that the mixer takes up 9 spaces. So a 8 top is too small and a 10 top was one size to large) With the extra rack space on top I put a power conditioner a rack space above the mixer. The bottom 4 spaces are sturdy but my only problem with this case is that you cannot use any of the rear of the case to rack mount as there is a piece of wooden rail where the rear rails would be. Also no side rails are not included. So if you have a larger amp that you don't feel comfortable beign held in with two screws when it weighs 35+lbs (I have a peavey 1500) you will need to put it on the bottom two rack space so it can rest on the bottom of the case. Gator also gives you a ton of screws with rubber grommet washers :)

Bought one of these combo racks a few months ago and I like. Price and quality are good which make the value excellent. Only drawbacks on features are no rails on the back side and the position of the handles make it a little awkward if you load it with 2 amps or more. This could be fixed if the handles were 2 inches forward. Otherwise I would recommend it to any DJ/musician on a budget just starting out.
