RackPath1U 4-Post Server Rack Rail, 20.2-32 Inch Adjustable Depth - 110lbs Capacity

Very sturdy 4-post mount. Would buy again if I needed another one.

These were easy to assemble and install. The various adjustable length allows easy adjustments for different depth racks. I did not find an easy way to use included screws to thread through rack ears to secure the chassis to the rack. Chassis needs to stick out to accommodate the round head screw.

Using to hold a 3U server. Works good to hold the server in place on the rack. Since the server has nothing over it, it is easy to access and work on even though it is not easy to pull out as it would be with normal rails.

I use these rails to hold a ~75lb UPS at the bottom of my rack. They work very well and feel very secure. Be aware that if you mount them as they are mounted in the picture, the rail mounting hardware may interefere with the rack ears of whatever you intend to put on the rails. For this reason I mounted the rails upside down, so the UPS rack ears can mount flush. This cost me 1U of space, but I'm happy with it. Alternatively, you could try to mount through the rail hardware, or zip tie whatever you're mounting. Overall great value and would recommend.

I normally buy these types of shelf brackets to hold HP and Dell servers. I prefer this type of mounting rather traditional rail mounting. When you are maintaining your own data center, I have found that while rails are great, when you really need to remove the server from the cabinet, sometimes the server wants to stay on the rail kit and with only one person, you can struggle to remove it. That is why I use shelf kits.The challenge with this specific kit is that the inside dimension (width) will not fit a number of servers (HP DL-380 etc.). It is about 1/4 too narrow.I will use these for things like Cisco routers and firewalls.Bit sad.

Be careful installing these and adding any meaningful weight to them.

Easy to assemble, holds a lot of weight, does not take up too much vertical (height)The last point was important to me, since I had issues with other shelves whereby my equipment would not fit (since it is almost now full)

Bought two to support a Dell R710, and a Dell R520. They hold up great. Came with cage nuts, and extra hardware for rack.
