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.

Very nice pillowcases
Color: Haze Blue, Size: 2 Pack Standard(20"X 26")
Very pretty pillowcases. I washed them in cold water and dried them on low before using. They came out a little wrinkly but smoothed out on the pillow. The fabric is shiny and rich looking. It's not hot yet, here in Texas, but I am anticipating the coolness of these pillowcases to feel very nice. I appreciate the envelope closure. It gives it a finished look. There was no odd odor. They feel good like they'll last for a long time. I am a satisfied customer.

Body pillow covers
Color: White, Size: Body(20"X 54")
I ordered the body pillow covers. They fit my pillow perfectly and the fabric is smooth and silky, but I did not find them cooling.

Cooling King-Size Pillows (used on a Queen pillows to tuck the extra in)
Color: Navy Blue, Size: 2 Pack King(20"X 36"), Color: Navy Blue, Size: 2 Pack King(20"X 36")
🛏️ Product Review: Cooling King-Size Pillows (used on a Queen bed) ⭐ The Good • These are king-size pillows, which I actually love on a queen bed because I can tuck the ends into the fabric. • The fabric feels slick and cool, but you don’t slip off of it. • They feel cold to the touch right out of the package (which is wild). • I sleep extremely hot and even run fevers at night due to a medical condition (literally 101–102° sometimes), and these pillows still stay cool where I lay my head. • I’ve honestly never slept this well in my life. • For the price, you cannot beat them, and they go on sale often. • These beat any high-end version I’ve tried. • If you sleep normal-temp and not lava-hot like me, you’re going to be VERY comfortable with these. ⚠️ The Bad • The fabric does show crease lines. • If wrinkles bother you, this might annoy you (doesn’t bother me personally). 🔧 What I’d Change / Tips for Care • Don’t use fabric softener — it clogs the cooling fabric and ruins how it works. • Wash with unscented detergent + a little vinegar. • Dry on low heat only (do NOT dry on high if you want the fabric to keep working long-term). ✅ Final Thoughts I will literally never not own these again. If you sleep hot, night-sweat, or just want a pillow that actually stays cool — these are it. 10/10 recommend.

Love it but it stains
Color: Haze Blue, Size: 2 Pack Standard(20"X 26")
I love these but had to knock some stars down for a single reason. They are soft, the material is somehow both substantial and airy at the same time, and a smooth, silky (not satin), cozy texture. The color was exactly as pictured. The envelope style works great to keep my pillows covered. The fabric lays perfectly. I love sleeping on this pillow case. Took two stars off because every single atom of oil on my face stained it immediately and won't come out in the wash. Its not subtle. You can see anywhere my face has been, forever. I don't have some incredibly oily face or hair, I've never had this happen to another pillow case in my life.
