Units are strong, attractive, and work as expected. One issue is that the units themselves are rather thick. If you are mounting an item that doesn't have adequate clearance built into the height of the device, you likely won't be able to stack them tight without leaving a gap U.

Bottom line: If you have a rack, and you have rack mount-able servers, but you built them yourself or you have mixed-brands servers and don't want to deal with the $$$ OEM rails, you need these rails to mount your mixalottastic gear in the rack. I have several racks at home. Full size, half height, etc. The gear I put in those racks changes every few months. Switches and patch panels are easy. All 1U or 1U. Servers on the other hand are not. Rails for a Dell 2U server are not the same as HP 2U rails, nor SuperMicro 2U rails and so on. If you've ever sold your used gear, you know that the OEM-specific server rails you paid $100 for, aren't worth half that on the used market. And that stinks. A lot of that gear I buy used or build it myself. The gear never comes with rack rails and even if the rails are available, they cost 2x-3x what these rails do and possibly doesn't even fit in your not-36U-or-more-deep-home rack. These rails are the answer. They are built from heavy-gauge steel. They even come with cage nuts and screws. They may seem expensive, but after you put your first set of these into your rack and cram your home-built, 4U GPU/NAS/AI server box thing that weighs 99 pounds into the rack and there's no drama, you'll wonder why you didn't buy them sooner. Highly recommended.

pros: well packaged quick delivery solid and strong rack easily adjustable length (depth) cons: single 1RU server can't fit into 1RU space if rack space above is occupied, it (with 1RU server) occupies at least 2RU space (not tested a 2RU server) overall rating - very good, I recommend

Minimum length is way too long. Does not work on a 46cm short depth rack.

Highly recommended for home labbers out there for their servers. Instead of buying model specific or manufacture specific rails, you could go with this well made product for variety of rackable server cases. The mental construction is very high quality and the advertised 200 lbs is probably under what this can actually holds., Recommended. 5/5
