SDU12 — Heavy Duty Double-Sided Cantilever Rack Starter Kit (12')

Already have this starter unit? View the matching ADU12 Heavy Duty Double-Sided Cantilever Rack Add-On Kit →

The SDU12 is the largest configuration in the MECO Series 4000 Standard Heavy Duty lineup. At 12' tall with 48" arms on both sides and 32 total storage positions per bay, it's engineered for high-ceiling industrial facilities that need to store the longest, heaviest materials with maximum density — full-length structural steel, oversized pipe runs, and similarly demanding stock — accessible from both sides of the aisle.

Ships complete with 2 uprights, 32 straight arms, and a brace set. Arms adjust on 3" centers. Professional installation is required.

What's Included

• 2 uprights (12' height, 106" base length)
• 32 straight arms (48" length, 1,000 lb capacity each)
• 1 brace set (72" length)
• All hardware for assembly

Why the SDU12

32 storage positions — the most of any MECO cantilever starter kit — With 48" arms on both sides across 12' of height, the SDU12 delivers the highest storage density in the entire Series 4000 lineup.

Double-sided access for the longest loads — Arms extend 48" from both sides of the upright, accommodating the widest bundles and longest materials while allowing forklift access from two aisles simultaneously.

Grows with your operation — Add ADU12 add-on units at any time to extend into a continuous double-sided row using shared upright frames.

Forklift accessible from both aisles — Open design on both sides supports efficient two-direction loading and unloading in high-throughput industrial storage environments.

Floor Anchors (Required, Not Included): Uprights must be anchored to the floor before use. MECO recommends a minimum of 2 anchors per base — 1 in the front and 1 in the back on opposite sides of the base. Each base has holes for up to 4 anchors. Recommended anchor spec: ½" × 4¼". Anchors are not sold by MECO and must be sourced independently. Building codes vary by location — consult local codes for specific requirements.

Series 4000 Standard Heavy Duty Double-sided Starter Units — Model Comparison

Arm capacity is set by arm length. Upright capacity is lower on taller uprights and with longer arms, so check the upright rating for the height and arm length you choose. All capacities are per MECO Omaha specifications based on evenly distributed loads.

Need single-sided storage? See the SU8, SU10, SU12 single-sided starter units.

Specifications

Important: Capacities are based on evenly distributed loads. Unit must be anchored to the floor per assembly instructions.

Customization Options

Arm Lips (L Suffix)

Bolt-on 2" arm lips are available for all 12 MECO cantilever rack SKUs in this lineup, including this model. Lips extend 2" above the arm surface and are used to retain cylindrical loads — pipe, tubing, round bar — that may otherwise roll off the end of the arm.

• Applies to both arms and bases — lips bolt on to every arm and base in the unit
• No extra charge if ordered with the rack — add the "L" suffix to the model number at time of purchase (e.g. SM6 → SM6L) and lips are included at the same price
• Can be ordered separately later — lips can be field-installed at any time after purchase, though a separate order and charge will apply
• Non-structural — lips are a retention feature only and are not intended to bear any portion of the load
• Factory punched — all MECO arms are factory punched to accept bolt-on lips, so no drilling is required

To order with lips, contact us at support@mywarehouseworld.com or (929) 577-4339 and we will place the order with the L suffix at no additional cost.

Additional Customization Options

Contact us to discuss any of the following configurations:

Inclined Arms — For cylindrical loads that tend to roll, inclined arms pitch at 20° (approximately 4.36" per foot) to keep material secure on the rack.

Bolt-On Pipe Sockets — Field-installable pipe sockets (1⅜" inside diameter) provide an additional stop at the end of the arm for round stock and tubing.

Drop-In Deck Support Saddles — Convert the SDU12 to a decked system for storing boxes, cartons, or furniture. Pre-engineered to accommodate 2×4 cross supports.

Custom Colors — Available at additional cost.
