The SKB Cases 3SKB-R904U30, 4U 30-inch Deep rSeries Shock Rack Case feature a depth of 30" from front to rear rail to accommodate deeper servers, with lid depths of 4.5" per lid. All 3SKB Series Roto Shock Racks feature a compound hinge system that allows the lid to swing out and completely around to lie flat against the main body of the case. This also enables effortless removal/reinstallation of the lid with a simple lift motion.

Both front and rear lids are designed to protrude into the base of the case approximately 1" with a unique double wall structure that makes them incredibly rigid where this intersection occurs, providing MIL-SPEC sealing characteristics with significantly fewer latches than most competitive cases. This revolutionary design allows for rapid deployment in an up-right configuration, even when stacked -- 3SKB Roto Shock Racks are the only shock racks in the marketplace today that will open front and back while stacked.

The inner rack chassis is built of high strength / lightweight aluminum alloy and 11 gauge hot rolled carbon steel rack rails to DIA-310 standards, creating an H-shaped frame that provides maximum strength. Shock and vibration mitigation are accomplished with eight (8) elastomeric isolators rated for a payload range of 40 - 150 pounds in a standard configuration, and up to 300 pounds in a special-order extended payload configuration allowing adequate sway space for ambient air circulation and heat dissipation. The rack rails come pre threaded for standard 10-32 hardware and mounting screws are included.

What an excellent wrist rest! Except for this one thing....
Color: Walnut Wood, Size: Large
This is a solid piece of wood with great quality. Fantastic large rubber grips on the bottom (left and right sides only). Pro: I use it for editing and gaming. And though I thought the wood might be a bad choice in the long run, it turns out it's pretty nice. Not as comfortable as a gel rest but I knew what I was getting when I ordered it. I buy things for function AND aesthetics. I love how this looks. The uniqueness is really something. I got the natural one instead of the black so that the grains and lines can be easily seen. Con: Unfortunately, after almost 2 months, the wood has warped some. Not enough to effect my typing but, enough that I notice it. The warp is the kind where the opposite angled corners go up and down. While the other 2 corners are fine. In my case, the top left and bottom right, when pressed independently, rock the wrist rest. The top right and bottom left stay grounded. This is why I took a star off. Because there's no way this should be happening. So, looks and quality are up there. The rubber grips are solid. Why it's warping is puzzling to me. NO liquid wasted on it. Or, extreme temperature changes have happened. I've made sure the rubber grips. And that the surface the rest sits on (a glass mouse scrolling top by Superglide) is clean. Yet, I get this slight rocking. It bugs me this all happened right after the return window closed. I would've simply exchanged it. I love it too much. I mean, this is, again, a SOLID piece of wood. Maybe this won't happen for everyone. I mean, it's wood. Eh I would still recommended this regardless.

Fantastic Product
Color: Walnut Wood, Size: Small
This is very nice! I type all day for my job and this made a big difference. It's very comfortable and supportive. Im allergic to latex rubber, which is in most gel options. It's really nice to have a safe, effective alternative

Beautiful, Solid Real Wood Wrist Rest
Color: Walnut Wood, Size: Large
This wooden wrist rest feels premium and the finish is super smooth — it’s noticeably nicer than foam or gel pads. Real wood looks great on my desk and still feels comfortable during long typing sessions. Definitely worth it if you want something stylish and functional.

Amazing item!
Color: Brown
Amazing quality feels very nice to the touch, decent size, on the bigger side if you’re looking for a smaller table organizer, but still great!
