Middle Atlantic CBS-MRK-31R: Caster Base for 31-Inch Deep MRK Series Racks

The CBS-MRK-31R caster base from Middle Atlantic Products is purpose-built to empower mobility, stability, and durable performance for your MRK Series 31" depth racks. This high-strength base is engineered to handle the rigors of demanding AV, broadcast, and IT environments while maintaining a clean, professional look that complements premium MRK deployments. Crafted from 11-gauge steel, the CBS-MRK-31R delivers a robust foundation that stands up to daily use, incidental impacts, and the test of time. At a compact 4.01 inches in height, it raises your equipment just enough to improve ventilation and reduce dust intrusion while preserving the rack’s accessibility for service and maintenance.

The MRK-31R is precisely matched to MRK Series racks, ensuring seamless integration, a secure fit, and a streamlined aesthetic that reflects Middle Atlantic’s reputation for quality engineering. A single base knockout is included to support efficient cable management and clean, organized routing of power and data lines as you reposition or reconfigure your setup.

how to install CBS-MRK-31R

Installing the CBS-MRK-31R caster base is a straightforward process designed to minimize downtime and maximize stability for MRK Series racks. Follow these practical steps to achieve a secure, reliable installation that preserves the integrity of your equipment layout while enabling easy future moves or reconfigurations.

  • Prepare the workspace: Clear the installation area and verify that you are working with MRK Series racks that are compatible with the CBS-MRK-31R. Confirm floor flatness and remove any obstacles that could interfere with positioning or movement.
  • Inspect components: Unpack and inspect the caster base for any shipping damage or missing hardware. Confirm that the 11-gauge steel construction and dimensions match your MRK rack specifications.
  • Position the base: With the rack’s base area accessible, align the CBS-MRK-31R so that its mounting footprint sits flush against the rack’s bottom frame or designated mounting points. Ensure the knockout opening aligns with your planned cable routing path if you intend to use it.
  • Secure the base: Use the manufacturer-recommended fasteners and mounting pattern to attach the caster base to the MRK rack. Tighten all hardware to ensure a solid connection, taking care not to overtighten and deform the rack framework.
  • Check alignment and stability: Once secured, verify that the rack sits level and that the base remains square with the rack’s frame. Gently test rolling motion to confirm smooth caster performance and inspect for any binding or uneven contact with the floor.
  • Route cables and power: If using the base knockout for cabling, route cables cleanly and secure them to minimize movement during relocation. Leave sufficient slack to prevent strain on connectors and to allow easy repositioning if needed.
  • Test mobility and load distribution: Slowly move the assembled rack to verify that the base maintains stability under load. Validate that there is no tipping risk and that weight is distributed evenly across the footprint.

Ewwwwww yuck awful
Color: Large - Obsidian Oasis
Gel moisturizer Sounds like a great idea right?? Ewwwwww! It’s so gross! They are hot feeling, sticky, and sooooo slippery. I was hoping to wear them overnight to help my dry cracked feet but you can’t walk in these! Not even to the bathroom. Honestly I wore them once, saw no difference, and threw them in the garbage.

The answer to calloused feet.
Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
If you have dry callused soles, these are your answer. All my calluses left and my feet were very soft. They should not be walked in unless you are very, very careful as you will slip and fall. I stopped using them for a while and all my problem calluses are back, even when I use lotion at night. They tell you not to sleep in them, I don't know why. I do put these on at night and end up taking them off later as they're not comfortable to sleep in.

Slippery when wet!!!
Color: Pink & Beige, Size: Medium/Large(fits size 8 to 11)
“These moisturizing slippers are actually really comfortable and feel great on the feet. They’re soft, cozy, and do help moisturize while you wear them. I also think they’re a good value for the money. The only downside is that once your feet get moisturized, they can get slippery inside the slippers, so I wouldn’t recommend walking around too much in them. Better for relaxing and letting your feet soak up the moisture than for being up and moving around.”
