Vertiv GL42UEX-75120B-MM-SC 42U Shock Crate for Server Rack Enclosures

Overview

The Vertiv GL42UEX-75120B-MM-SC is a purpose-built shock crate designed for the safe transportation of 42U rack enclosures — specifically those with a 750mm width and 1200mm depth footprint. When you're moving a populated or unpopulated rack across a data center floor, between facilities, or via freight, a standard shipping pallet isn't enough. This shock crate provides the structural containment and impact absorption that prevents costly damage to servers, UPS systems, switches, and patch infrastructure during transit. If you're sourcing Vertiv rack infrastructure and need to move it safely, the GL42UEX-75120B-MM-SC is the matched shipping solution for that enclosure class.

Shock crates in this category see use across enterprise data center migrations, colocation deployments, and government facility buildouts — anywhere the cost of equipment inside the rack dwarfs the cost of the crate itself by orders of magnitude. Protecting a $50,000–$500,000 rack payload with the correct matched crate is straightforward risk management, not optional infrastructure spending.

Key Features

• 42U Capacity Match: Sized to fit a full 42U rack enclosure — the most common height in commercial and enterprise data center deployments. If your rack is shorter (e.g., 24U or 36U), you'll want a crate matched to that height rather than relying on padding to fill the gap.
• 750mm Width: Matches the 750mm-wide rack footprint common in Vertiv's Geist and SmartRack lines. Confirm your enclosure's external width before ordering — a 600mm-wide rack requires a different crate SKU.
• 1200mm Depth: Accommodates 1200mm deep enclosures, which are standard in environments housing full-depth servers, blade chassis, and high-density compute or storage nodes. Shallower 1000mm or 800mm racks need a different crate to ensure a secure fit without movement inside the crate during transit.
• Black Finish: The black colorway (GL42UEX-75120B-MM-SC) is the standard production variant for this enclosure dimension — consistent with Vertiv's rack accessory line and practical for facilities with color-coded infrastructure management.
• Shock Crate Construction: Shock crates provide substantially more protection than wood crating or cardboard alone. The engineered crate structure is designed to absorb transit impacts — including forklift handling, truck vibration, and drop events — that would otherwise transfer directly to mounted equipment.
• SKU Specificity — MM-SC Suffix: The MM-SC designation in GL42UEX-75120B-MM-SC encodes the 750mm (M) x 1200mm (M) dimension pair and the shock crate (SC) product type. This prevents substitution errors when ordering — the part number is your confirmation that you're getting the correct crate for this specific enclosure size class.

Integration & Compatibility

The GL42UEX-75120B-MM-SC is dimensionally matched to server rack enclosures with a 750mm x 1200mm external footprint. It is used in conjunction with Vertiv's 42U rack product family — confirm your enclosure's external dimensions against the crate's interior fit spec before finalizing an order. This crate does not install into a data center environment; it is a transit and logistics product that is used once or retained for future moves. Organizations managing multi-site data center infrastructure often retain shock crates for scheduled rack migrations and decommission cycles.

If you're planning a phased data center buildout or a rack-level migration, coordinate crate ordering with your project timeline — lead times on specialty transit hardware can affect deployment schedules. For enterprise procurement teams quoting large rack deployments, pairing a rack enclosure order with the matched shock crate SKU at time of purchase eliminates sourcing friction later.

Frequently Asked Questions

Q: What rack enclosure dimensions does the GL42UEX-75120B-MM-SC shock crate fit?

A: The GL42UEX-75120B-MM-SC is sized for 42U rack enclosures with a 750mm width and 1200mm depth. The MM-SC suffix in the part number encodes these dimensions (750mm x 1200mm) and the shock crate product type. Confirm your enclosure's external footprint before ordering.

Q: Can I use the GL42UEX-75120B-MM-SC shock crate for a 600mm wide rack?

A: No. This crate is matched to 750mm wide enclosures. Using it with a 600mm wide rack would leave unacceptable lateral clearance inside the crate, increasing the risk of movement and impact damage during transit. Order a crate SKU matched to your actual enclosure width.

Q: Is the shock crate reusable for future rack migrations?

A: Shock crates are generally engineered for the protection of rack enclosures during freight and facility-to-facility moves. Many organizations retain them for future migrations. Inspect the crate structure after each use to confirm it remains fit for purpose before reusing.

Q: Does the GL42UEX-75120B-MM-SC ship with the rack enclosure, or is it ordered separately?

A: The shock crate is a separate SKU ordered independently of the rack enclosure. If you're quoting a full rack deployment and need transit protection, add the GL42UEX-75120B-MM-SC to your order alongside the enclosure — it does not automatically bundle with rack purchases.

Q: Is this product available for project-volume orders?

A: Yes. For data center buildouts requiring multiple rack enclosures and matched shock crates, pre-sales engineering support is available for volume quotes. Contact the team for project-level pricing and lead time confirmation.

The GL42UEX-75120B-MM-SC is a dimensionally specific transit solution — the 750mm x 1200mm footprint encoded directly in the SKU suffix means there's no guessing about fit. When I'm quoting a rack migration project, the first mistake I see is teams ordering generic crating and then improvising foam packing to compensate for dimensional mismatch. That movement inside the crate during freight is how you end up with bent rail ears and cracked switch faceplates before the rack ever gets mounted.

Technical Highlights:

• 42U Height Match: Full 42U capacity means this crate handles the tallest standard enclosures in a commercial data center stack — no need to source a custom crate or stack multiple shorter units.
• 750mm x 1200mm Dimensional Precision: The MM-SC suffix is not cosmetic — it locks the crate to a specific enclosure footprint class, eliminating substitution errors on large procurement orders where dozens of crates and racks ship simultaneously.
• Shock Crate Construction: Purpose-built shock absorption versus improvised wood or cardboard crating — a meaningful distinction when the rack payload includes blade servers, dense storage arrays, or pre-wired patch infrastructure that can't be easily re-terminated if damaged in transit.

Deployment Considerations:

• Verify your enclosure's external width and depth — not the nominal internal U-space — against the 750mm x 1200mm crate spec before ordering. External dimensions on populated racks can differ from nameplate specs when cable management accessories are installed.
• This is a logistics and transit product, not a permanent installation component. Factor lead time into your project schedule — shock crates are often overlooked until the day before a rack ships, which is too late if the item needs to be sourced from distribution.

The GL42UEX-75120B-MM-SC is the right call for any enterprise data center migration, colocation deployment, or government facility buildout where 42U racks in the 750mm x 1200mm class are moving via freight — and where the cost of the equipment inside the rack makes improvised crating an unacceptable risk.
