Reliable Hardware Company RH-4-SRR-A 4U Full Hole 4 Space Rack Rail Pair (Fоur Paсk)

Awesome stuff. I have made several DIY wooden racks with this stuff now, and it makes every project easy-peasy. Just place your boards with exactly 19" between them (pro-tip: use an actual piece of rack gear to measure the spacing), place this rail in, and screw it in. The attachment holes are dual sized, so it will work with whatever screw size you have, and you can stagger the screw locations so they don't run into the neighbor.The rails are rugged, the threads are great, the build-quality is awesome. And they are sold in pairs, so don't order twice as many as you need like I keep doing.

The product works fine and as described, but I was really irritated by how misleading the product picture is. I thought I would be getting three different sizes pairs, I thought it was a killer deal. Granted I should've read the description, but I believe that having that as the main picture is still false advertising and really misleading. Make sure you read to find out which size you are getting because this is the same picture they have on all the sizes. Get individual product pictures please!

I bought two sizes, the 7 inch rail and the 43 inch rail. They arrived in great condition. They were painted black and were pre-threaded. What I don't like about them is that the pre-threaded 10-32 holes are clogged with paint. There is enough paint in the threads to make screwing them very difficult. Some of the holes are cross threaded already, so your screws go in at an angle.

exactly what i needed to mount my 4-space midi patch bay into the BACK of my rack case.i have a patch bay with the I/O on the front, which would mean a mess of unsightly totally-in-the-way midi cables sticking out the front of the case had i mounted it along with my synths (and take up valuable rack space)popped this thing into the back side of the rack case and mounted the patch bay right in. good, solid construction and all the holes are where they should be lolbasically you can add a rack mount anywhere you might need to using these, as they come in a variety of lengths!

Metal rails are metal rails but saying the threads are 32 when they are more like a non standard 22 tpi therein causing multiple attempts to source the correct bolts earns two stars solely for the cheap cost of these. The closest standard thread was using sheet metal screws, nowhere as tight threading as a 32 tpi machine bolt threading. It's proprietary no wonder their bolts seem to work best.

The one thing I was not a fan was that there is paint inside the threads. So it feels like your cross threading a bolt. When I’m reailty it’s just a layer of paint.The other issue my set has was the edges. Sharp! Be careful when handling them.Had to take a file to round out the sharp edges.

I recently decided to go full-on home wired LAN, and not being one to half-a$$ things, built a small networking rack. The 4u rails were perfect for my setup. There was some powder coating in the threads, but that is to be expected and running a screw in and out a couple times got the holes cleared out nicely.

Price is ok, but unless you have a tap handy I would get something else. I had to use the screws I had to basically retap all the holes. Took about three times longer to mount a few pieces of equipment then it should have.
