Sound Town2-Pack 4U Steel Rack Rails, with Black Powder Coated Finish and Screws (ST-RR-04U)

Ajuste perfecto

Las reseñas que se quejan de los tornillos o no saben usar un desarmador o era una versión anterior, lo único que tienes que hacer es alinearlo bien y dar las primeras vueltas con un poco de cariño.... Hasta vienen con tornillos para madera, para instalar los rieles al mueble... El acabado es perfecto, números claros y legibles, material grueso y sólido. voy a comprar otro par

These are incredible quality for the price. They are sturdy enough to hold my two units with just the rails and screws alone.(picture 1+2)There are plenty of complaints about the screw holes being a little tight but all you have to do is use a screwdriver with a bit of pressure and they'll go right in. Just be sure they are lined up so you don't strip the threads. And honestly you need them that tight, if they were looser your equipment wouldn't be secured. I assembled this in 5 minutes with only a screwdriver and I'm a weak-wristed lady so if I can do it without needing power tools or having to cut the holes wider then anyone can.I saw other comments about the holes not lining up correctly. You do have to line up the top and bottom of your equipment with the lines. Were a line is painted, the adjacent screw holes are slightly closer together.(picture 3. Sorry my handwriting is terrible.) If you don't line up your equipment with the lines then yes, the screw holes on your equipment will not line up properly. That seems kinda obvious, but people like to complain superfluously in Amazon's rating section. It's easier to blame the product than admit one's own ignorance.Plenty of screws and washers were included with the rails but they did not come with nuts, so if you're using heavier equipment you might want to get some. I am not using nuts in the pictures as my stack is holding up fine without them. I have not tested just how much weight the threads can handle, so better to be safe than sorry.I will be purchasing more of these for the rest of my equipment. These exceeded my expectations.

I'll get to the point. The wood screws they give you are for 3/4 inch plywood, which is not always needed when you build a rack. I chose 1/2" baltic birch for a smaller custom enclosure. So these screws are too long and will go right through! They really should mention that!Rather than try to locate a shorter screw (which probably would have failed), I decided to stack 5 of the included washers to stand off the screws. It appears to have worked, even though "standard practice" is 3 washers maximum.The rails are bent just a little more than 90 degrees so they slant inward just a hair. I don't know if that will interfere with mounting equipment. I will come back and edit if there's more to add!

Great for making your own rack system.
