AC InfinityVented Cantilever 1U Universal Rack Shelf, 10" Deep, for 19” Equipment Racks. Heavy-Duty 2.4mm Cold Rolled Steel, 60lbs Capacity

This 1 RU shelf was perfect for mounting three small NDI-to-SDI converters into a portable production rack where space was limited and I needed good airflow for the converters as well as the rest of the equipment.The shelf is solid, not flimsy at all, and the slots gave me flexibility in arranging and securing the devices. I originally used 1/4-20 bolts (had to drill into the shelf), but later switched to zip ties because the pan head bolts didn't allow enough clearance to the equipment below.I'm going to be building another portable production kit and this will likely be purchased again for it.

Just put this into my rack, supported by all 4 bolts. I've got a heavy UPS (https://www.amazon.com/dp/B06VY6FXMM?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1) on it on it's side and I see no sag at all (side to side or front to back). Bolts line up just fine on this rack (https://www.amazon.com/gp/product/B07YYMSFP1/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1). Gotta make sure you actually put it a proper U position on the rack. You can't straddle U's as the bolt holes aren't uniform.

It's surprisingly heavy and sturdy.

This is a sturdy rack shelf. As others have noted, the rack has a rounded off lip on the bottom. Looking at other racks on Amazon, they all seem to do this. This does interfere with what’s below it. However, there is an easy fix for this. Just put an extra plastic washer behind the rack face on the shelf and that puts it forward enough that the lip won’t hit the equipment below.

Overall this shelf is really good. Good build quality. Sturdy. And great value for the price.My only complaint is that this shelf has a bottom lip below the shelf that extends below the 1U size and can interfere with components below it. For example, trying to install a blank panel below this shelf is only possible if you install the blank panel before installing this shelf. Otherwise it's basically impossible to tuck the blank panel underneath that lip that extends below this shelf.Overall, great value for the money, and gets the job done. Just be careful about using it above another component with that bottom lip.

This is the second one of these I've purchased. They are very well made and will stand up to any load short of something stupidly heavy like a car battery. I've purchased probably a dozen different rackmount shelves over the years. A few are lousy and I wouldn't buy again. Most are "good enough." A few are "fantastic" and this one is definitely in that category. The shelf looks and feels to be 1/8" steel (or close to that thick). It's heavy and does not flex. At least on the one I received, the paint job or powdercoating is thick and smooth and should last. Icing on the cake are all the slots, which while their primary purpose is ventilation, they are great for running zip ties through to secure all those little boxes that aren't "rackmountable" and why you probably bought this shelf to begin with. Comes with 10-32 screws to mount the shelf and cage nuts in case your rack uses the push-in style cage nuts vs. having threaded rails. Could not make this shelf better if I could wish it into existence. Highly recommended.

There are a couple things I'd highlight about this shelf. The biggest characteristic I want to highlight is that it has been carefully made to eliminate sharp edges and corners. It feels smooth and has a surprisingly nice finish to it. With a lot of rack gear you run the constant risk of cutting yourself, but this shelf is actually very nice. The material is heavy enough to support reasonable loads on a standard cabinet and because it is a cantilever half depth shelf, it only affixes to a single rack rail.The shelf also includes ample opportunity on the sides to affix cables with tie straps. I do not think the venting in the shelf itself would work well for tie straps, but there are nice long slots on the side that lend themselves well to aiding in cable management and for passing cables from the shelf in an organized fashion.The product is nicely packaged and includes rack screws and nuts, which work perfectly with square hole racks.I will be ordering an additional shelf for my humble home rack and comfortably recommend these to anyone.

I had no issues with the product being damaged out of the box. It's strong, has a good powder coat finish, no sharp edges. Great product.
