Vertiv SC128442 Side Column Add-On Rack Enclosure, 84"H x 12"W x 42"D
Overview
The Vertiv SC128442 is a 12-inch-wide side column add-on enclosure designed to expand the usable space alongside Vertiv ES rack systems. At 84 inches tall and 42 inches deep, it matches the footprint of the ES enclosure family's 84"H x 42"D models — giving integrators a flush, coordinated installation without gap-filling workarounds. If you're deploying a Vertiv rack solution and need cable management, blanking, or auxiliary mounting real estate on the side of your primary enclosure, the SC128442 is the structured answer.
The 12-inch width is the key planning number here: it provides enough internal clearance for vertical cable managers and patch routing without consuming the floor space of a full-width additional rack. Paired with the matching 42-inch depth of the ES series, the side column sits flush front-to-back — no overhang, no bracket shimming. This matters in raised-floor data centers and security head-end rooms where physical alignment between adjacent cabinets directly affects cable bend radii and airflow containment.
Compatibility
The SC128442 is verified compatible with the following Vertiv ES enclosure models within data center rack enclosures:
- 84"H x 42"D ES models: SC128442, SC68442, SCP8442 — direct depth and height match, no adapter required.
- 84"H x 48"D ES models: SC128448, SC68448, SCP8448 — height matches; note the 6-inch depth difference when planning floor tile cutouts.
- 91"H x 42"D ES models: SC129142, SC69142, SCP9142 — compatible, but the 7-inch height delta means the side column will sit lower than the primary enclosure top.
- 91"H x 48"D ES models: SC129148, SC69148, SCP9148 — compatible with the same height offset consideration.
- 79"H x 42"D ES models: SC127942, SC67942, SCP7942 — compatible; side column will stand 5 inches taller than the primary unit.
- 79"H x 48"D ES models: SC127948, SC67948, SCP7948 — compatible with depth mismatch noted above.
- LRB accessory rails: LRB-12, LRB-12A1, LRB-12A2, LRB-24, LRB-24A1, LRB-24A2 — all ES sizes supported, enabling integration with the full Vertiv lateral rail bracket accessory line.
For full rack enclosure planning, cross-reference the depth of your primary ES unit before ordering — the SC128442's 42-inch depth pairs cleanly with 42"D ES enclosures and is workable with 48"D units where floor tile alignment is not a hard constraint.
Frequently Asked Questions
Q: Which Vertiv ES enclosures is the SC128442 directly compatible with?
A: The SC128442 is verified compatible with Vertiv ES enclosures in 79", 84", and 91" heights and both 42" and 48" depths, including models SC129148, SC69148, SCP9148, SC129142, SC69142, SCP9142, SC128448, SC68448, SCP8448, SC128442, SC68442, SCP8442, SC127948, SC67948, SCP7948, SC127942, SC67942, and SCP7942. It also supports all LRB-12 and LRB-24 lateral rail bracket variants.
Q: What are the physical dimensions of the SC128442?
A: The SC128442 measures 84 inches high, 12 inches wide, and 42 inches deep.
Q: Does the depth of the SC128442 match all compatible ES enclosures?
A: Not all. The SC128442 is 42 inches deep, which matches 42"D ES enclosures exactly. It is also listed as compatible with 48"D ES enclosures, but there will be a 6-inch front-to-back offset — factor this into cable management and floor tile planning before installation.
Q: Can the SC128442 be used with Vertiv LRB lateral rail brackets?
A: Yes. The SC128442 is compatible with the full LRB accessory line including LRB-12, LRB-12A1, LRB-12A2, LRB-24, LRB-24A1, and LRB-24A2 in all ES sizes.
