  • Designed for GRK Series Racks: The GRK PRO Rail PR, 40SP is engineered to integrate seamlessly with Middle Atlantic GRK racks, ensuring precise alignment with rack mounting holes and consistent rail spacing. This compatibility translates to smoother installation, fewer alignment issues, and reliable support for critical equipment. The rail’s geometry complements GRK profiles, contributing to a cohesive, professional rack system that delivers repeatable performance in multiple deployments—from small server closets to larger enterprise installations.
  • 40-Space Capacity with 70" Length (Cage-Nut Style): Offering a substantial 40-space (70") cage-nut style rack rail, this component provides ample room for a wide array of 19-inch equipment. The cage-nut style design facilitates quick, tool-free mounting and removal of components, reducing downtime during upgrades or reconfigurations. Organizations gain the flexibility to consolidate gear efficiently while preserving clear pathways for cooling and cable management, a key advantage in densely populated racks.
  • Durable Steel Construction with Powder-Coated Finish: Built to endure the demands of busy facilities, the GRK PRO Rail PR features rugged steel construction paired with a protective powder-coated finish. This combination resists everyday wear, reduces the risk of corrosion in potentially humid or demanding environments, and helps maintain a professional, uniform appearance across the rack. The robust build also supports stable long-term mounting for heavy or frequently accessed equipment, contributing to reduced wobble and improved mounting reliability over time.
  • Rack-Mountable Form Factor for Reliability: The rail’s rack-mountable form factor ensures secure attachment to vertical rack rails and consistent alignment across the entire enclosure. This reliability helps prevent creaking, misalignment, or equipment shifting when inserting or removing devices. For facilities that rely on uptime and predictable maintenance windows, the PR 40SP rail provides a dependable backbone that supports orderly, repeatable setups and easy future upgrades without sacrificing stability.
  • Organization, Accessibility, and Future-Proofing: Beyond simply holding equipment, this rail supports organized, scalable rack layouts. The cage-nut mounting system allows for flexible accessory placement and straightforward reconfiguration as equipment inventory changes. By maintaining clean cable routing, predictable airflow, and quick access to rear panel connections, technicians can perform maintenance faster, reduce troubleshooting time, and keep critical systems online with minimal disruption.

Way too narrow
Size: 9.5 Wide, Color: Burgundy Polished Full Grain
I ordered a wide in this shoe, but it was still way too narrow. I had to return them. Otherwise, it looked like a nice quality shoe.

I usually wear 11.5's, but I buy 1/2 size smaller to accommodate for stretch. Leather relaxes.
Size: 11, Color: Burgundy Polished Full Grain
5 STARS: These shoes are awesome. I keep coming back for more. I have major foot problems, have tried all kinds of shoes, orthotics, and inserts... but believe it or not, these shoes work better than any of that stuff. I wear them daily. I buy lots of them, for home, for church, and I'm getting my first pair of J&M boots today, for winters in Indiana... Brrrr

Sleek, upscale and supremely comfortable
Size: 9, Color: Cognac
I did not know that Marc Joseph makes hands free slip ins. I own four pair of Skechers, and I thought they were the only game in town. I decided that I wanted a pair of business casual pair of wingtips. I already own two pair of Skechers Mark Nason wingtips in blue and black nubuck, so I bought a pair of their cognac colored. Perfectly fine shoes, but when they arrived, I didn't like the color, so the search was on! I found these cognac-colored Mark Joseph's and hands down, they fit the bill for what I was looking for! I actually bought two more pair of Skechers in the brown family in the same oxford, elastic lace style: One pair of another style of their Mark Nason line and one pair of their Garza line. So now I am comparing three pair of Skechers to the Marc Joseph's. Obsessive, I know :). Luckily, I have a Skechers store near me for easy returns. The look I was going for is a sleek, business casual that I could dress up or down. Three things that I love about the Marc Joseph's are the beautiful cognac finish: the white yet lower profile soles and the more formal, narrower toe style. The MJ's nailed it with the color. They have a slightly darker, more lustrous and glossier look than the others. The color alone looks classier and pairs well with black pants which I wear for work almost every day. The white soles are exactly what I was looking for. The visible rise is probably about a third of the thickness of the others and are a much more subtle, classier look. They offset the cognac color nicely but are not that in your face, sneaker looking, thick white sole. When I was comparing them to the others right out of the box, I thought they would be too narrow and tight because they looked sleeker and narrower than the others. But they fit perfectly and were very comfortable right out of the box. Upon closer inspection and comparison, I realized the narrower, sleeker look is because the eyelets for the elastic shoelaces are closer together that give the illusion that the shoe is narrower. They compensate for what might create a tighter fit across the top of your foot with two stretchy "gores" they are called on either side of the upper part. The "slits" are nicely finished, and you can't see the stretchy part and add a nice design touch to the shoe. But between them and the elastic shoelaces, they must stretch just enough to make them extremely comfortable across the top. So, if you have a high instep/arch, they should accommodate it nicely. Last but not least, they are very comfortable shoes. I wear a size 8 1/2 to 9 and my foot is slightly on the wide side. I bought the size 9's and they fit perfectly. If you are between sizes or have wider feet, you may want to size up a half size. Because the Skechers have much thicker soles, they might be slightly more cushioned, but the MJ's are cushioned more than enough for my purposes and very comfortable. Plus, they actually just feel better on my feet. I can't speak to how durable they will be as I just got them, but so far, so good. So, there you have it. I rely on other people's reviews a lot when buying online, and especially for shoes. I know it's always a crap shoot, particularly when buying shoes online, so I hope this review helps. Everybody's feet are different, but I highly recommend these.
