StarTech.com 1U Adjustable Mounting Depth Vented Rack Mount Shelf - 175lbs / 80kg - Fixed Server Rack Shelf

Fits good, Works well. I would buy it again if the need arises.

伸縮式棚板 を購入しました 19インチラックのケージナットと固定用のネジもついていて 良い製品だと思いますが ネジがM６なのでご注意 (自分は前に使っていた機器のケージナットと交換しなきゃいけなかった) 前左・前右(この2つは奥行きの短い金具) 後左・後右の4つの金具と 棚板で構成されていて各金具を棚板にねじ止めする ネジは、プラス頭のボルトとナットでねじ止めでほかの人も書いてますが ねじ止めがしづらいですが 自分の環境の場合、奥行きが長いラックでしたので 前の金具2つをしっかり締めてから 後ろの方は金具が長いので そちらを後にするとネジ締めし易かったです。 製品自体重いですが、棚板の強度はその分文句なしです

I purchased this product from Amazon.com to provide a working shelf for my Startech 25U 4POSTRACK25. Rather than use a traditional all-in-one KVM shelf with keyboard, touchpad and monitor, I decided to build my own setup using this rackmount shelf and other parts. I'm building PC's instead of servers, which those other prebuilt KVM shelves are oriented toward. Those cost about $500 for a basic model to well over $1000 depending on mfr. and features to use with servers. This allowed me to pick and choose every component, and change them as needed, at much lower cost. I can standard- ize on any keyboard, mouse and monitor I want, and switch any one at any time. I built around the TRENDnet TK-802R PS/2 VGA KVM 8 port rackmount switch. This shelf from Startech is very nice, quite sturdy and well-made. To assemble it one should be mechanically adept because the instructions are rather sparse, giving almost no direction. Even the pictures only help somewhat. The first thing to do is attach the drawer slide rails to the sides of the draw, after separating the slides releasing the black latch lever. The tapered end of the slide faces toward the rear of the drawer. Screw heads are inserted from the outside, and the washer, lockwasher, and retaining nut are then attached and secured from the inside of the draw. The stock picture on this product page is for mounting onto a 2 post rack. My pictures will make very clear what is the correct order and position of each part to install in a 4 post rackmount like mine. The smaller brackets then are attached to the outer rail. The holes only line up in one end to do this. The black drawer backstop inside the outer rail is towards the rear. Attach each outer side rail to the front using the screws into M5 cage nuts in the frame. Next attach the rear rackmount brackets at the same height in the rear of the unit, placing the outer slide into this bracket. Once the rear bracket is secured, you can insert 2 screws through the bracket and outer rail to mate this outer slide assembly. In all cases the screw heads are mounted INSIDE the bracket and rail, reversed of how the drawer screws are mounted. The washers, lock washers, and nuts face outside the sides of the slides. This is done in both instances because there is a ball-bearing slide assembly inside the outer rail, for clearance of the draw to move inside the slide mounts. Last step is to attach the handle to the drawer front as pictured, then insert the drawer into the slides similiar to a desk or file cabinet drawer. The handle is easily reversed to hide-away and exposes a flush flat side. I still have some cable management to do. The drawer was placed under the KVM to keep it exposed, and allow clearance for the mouse and keyboard wires, because the draw has no cable management. Some cable clamps after connection to the KVM will tidy all my AC, DC, printer, KVM, telco, USB and network cables once routed neatly in bundles. For less than $300, I built a flexible standard PC KVM rackmount system for up to 8 computers, and cascadable if I ever need to expand by using this Startech rackmount shelf drawer.

Solid rack shelf. While the shelf itself is of fixed length, the mounting brackets can be adjusted to proper depth. Which was pretty easy to do. 2 screws for each bracket (total 8 screws). Installing it in my rack was simple; probably took me an hour altogether. Though as you can see from my pics, I have full access from all sides. Might be more difficult to do in more enclosed racks. As you can see in the pics, I placed my tower server and other peripherals on the shelf. It's not flimsy, so I had no concerns if the shelf could support the weight or not.

I found that putting this in place was hard and really needs two people, then extending the shelf was also difficult and did not really work as expected, I have shorted my rack in order to accomadate this shelf but it should have been able to fit in the rack at half extended width. It is the same make as the rack. It is strong as it is fitted at both ends of the rack and will be more that strong enough to hold my NAS and now that I have shortened the rack the NAS will be able to pulled forward from the rack when I need to get to the back of it.
