If the Kendall Howard LINIER server cabinet you normally purchase is no longer available, don't choose a replacement based on rack height alone.
A proper server rack replacement should be matched to the equipment and installation it's actually serving.
GAW Technology has been informed that new production of Kendall Howard LINIER server cabinets is no longer being offered as of August 31, 2026. That means organizations standardized on LINIER cabinets should start identifying replacement options now — even if some original inventory is still around.
GAW Technology can help match existing Kendall Howard cabinets to standard, semi-custom or custom server rack solutions.
Start With the Kendall Howard Model Number
The fastest way to identify an appropriate replacement is usually the complete Kendall Howard model number.
LINIER full-size cabinets have spanned multiple model families, including the 3100-series and configurations such as 3100, 3101, 3103, 3106, 3107, 3108, 3130, 3140, 3141, 3170 and 3180.
These numbers surface differences that aren't obvious from the outside — the original rack may have been built with glass doors, solid doors, vented doors, removable side panels, or no doors at all.
Don't assume two LINIER cabinets with the same rack-unit height are identical.
Replacing a Kendall Howard 22U LINIER Rack
A 22U cabinet is often used where equipment needs exceed a small wall-mount enclosure but don't justify a full-height data center cabinet.
When replacing a Kendall Howard 22U LINIER cabinet, evaluate rack depth, equipment load, door ventilation, floor footprint, cable entry, and whether casters or levelers are required.
GAW Technology can help match existing Kendall Howard cabinets to standard (LINIER replacement guide), semi-custom or custom server rack solutions.
A current GAW option worth evaluating for both 22U and 27U replacements is the GAW 26U Network Equipment Cabinet.
Replacing a Kendall Howard 27U LINIER Rack
Kendall Howard 27U LINIER cabinets have been used for networking, telecom, server, security and A/V applications.
A replacement should be evaluated for usable equipment depth, not just U height — particularly important when servers, UPS equipment or deeper network hardware are involved.
Customers searching for a Kendall Howard 27U rack replacement should provide the complete model number whenever possible. Checkout our 27U replacement option page.
Replacing a Kendall Howard 37U LINIER Rack
A 37U rack presents an extra wrinkle because 37U is less common than industry-standard full-height configurations.
Depending on the installation, moving to a 40U, 42U, 44U or customized enclosure may provide a better long-term solution — but room dimensions, equipment height and existing rack rows should be reviewed before changing form factor.
GAW can evaluate the original 37U LINIER specification and recommend an appropriate replacement rather than simply bumping up cabinet height. Learn more about replacement options.
Replacing a Kendall Howard 42U LINIER Rack
The 42U server cabinet is one of the most common data center and equipment-room rack formats, so customers searching for a Kendall Howard 42U LINIER replacement typically have several alternatives to choose from.
But 42U alone isn't enough information.
The replacement still needs to account for rack depth, rail adjustment, airflow, doors, side panels, cable access, equipment weight and the overall environment. For high-density equipment, airflow may be the most important consideration; for controlled-access environments, locking doors and side panels may matter just as much.
Replacing a Kendall Howard 45U LINIER Rack
45U cabinets add vertical capacity and are often chosen where maximizing equipment density matters most.
Before switching to another 45U rack — or moving to a 44U or taller enclosure — confirm available room height, cable pathways, power distribution and installed equipment requirements. GAW can help determine whether the original LINIER dimensions need to be duplicated or whether the replacement installation can actually be improved.
24-Inch vs. 36-Inch LINIER Rack Depth: Why It Matters
Depth is one of the easiest specifications to overlook.
LINIER cabinets have been offered with roughly 24 inches or 36 inches of usable equipment depth.
A 24-inch-depth cabinet may suit networking, telecom, A/V and shorter equipment. Servers, UPS systems and other larger equipment may need substantially more depth.
When replacing a rack, measure the installed equipment — not just the exterior cabinet. Rear cabling, PDUs and connector clearance all eat into that space.
Vented, Solid or Glass Doors: Matching Airflow to Function
Door configuration affects more than appearance.
Vented doors support higher-airflow installations. Solid doors can help when isolation or restricted airflow is part of the design. Glass doors offer visibility while limiting direct access.
The right replacement should preserve the functional purpose of the original configuration — and if airflow requirements have changed since the original LINIER cabinet went in, a replacement is also a chance to improve the design.
Have an Existing LINIER Installation? Prioritize What Actually Matters
Organizations with multiple installed LINIER racks may want a replacement that visually and operationally integrates with the existing room.
An exact appearance match isn't always possible once the original product is unavailable, but critical characteristics can usually be prioritized.
GAW can review your existing cabinet's dimensions, equipment layout and operational requirements to determine what has to match and what can be improved.
Custom Replacement Options From GAW
One advantage of working with GAW Technology is that the replacement doesn't always have to come straight from another catalog. GAW manufactures custom server rack solutions when a standard cabinet doesn't adequately replace the original Kendall Howard configuration.
This is especially useful for specialized installations, unusual dimensions, airflow requirements, security needs, or customers trying to maintain an existing rack standard.
Kendall Howard Replacement FAQs
What is the best replacement for a Kendall Howard LINIER cabinet?
There's no single replacement for every LINIER model. The right one depends on rack height, depth, rail configuration, doors, airflow, load capacity and the equipment being installed.
What replaces a Kendall Howard 3107 rack?
The 3107 family includes LINIER configurations that should be matched by complete part number and specifications. Provide GAW the complete 3107 model number so the correct configuration can be evaluated.
The replacement still needs to account for rack depth, rail adjustment, airflow, doors, side panels, cable access, equipment weight and the overall environment. Review the 42U replacement options for GAW 44U, CableMAX and Cloud Cabinet paths.
What replaces a Kendall Howard 3106 server cabinet?
As with other LINIER models, the complete 3106 part number matters because height and depth can vary. GAW can compare the original specifications against available replacements.
Can I replace a Kendall Howard 37U cabinet with a 42U rack?
Possibly. It depends on available space, equipment configuration and project requirements. The extra height may provide useful future capacity, but dimensions should be checked first.
Before switching to another 45U rack — or moving to a 44U or taller enclosure — confirm available room height, cable pathways, power distribution and installed equipment requirements. Contact GAW Technology if the original LINIER dimensions need to be duplicated or the replacement installation can be improved.
Does the replacement need the same door style?
Not necessarily, but airflow, equipment protection, security and access requirements should be preserved.
Can GAW duplicate a discontinued Kendall Howard rack?
Depending on the requirements, GAW may be able to provide a standard, modified or custom cabinet that satisfies the same functional requirements. An exact duplicate isn't always necessary or desirable.
What information does GAW need to find a replacement?
Start with the Kendall Howard part number. If it's unavailable, provide rack-unit height, usable depth, overall dimensions, door type, equipment being installed, approximate weight, photographs and any project specifications.
Should I replace all my existing Kendall Howard racks?
Generally, no. Existing functioning cabinets don't need to be replaced simply because new production has ended. The real task is establishing a replacement strategy for expansion, new locations and future equipment needs.
Need a Replacement for a Kendall Howard LINIER Rack?
Send GAW Technology your Kendall Howard model number.
