AU10 — Single-sided Cantilever Rack Add-On Kit (10')

Need a starter unit first? View the matching SU10 Heavy Duty Single-Sided Cantilever Rack Starter Kit →

The AU10 is the Series 4000 Standard Heavy Duty add-on kit designed to extend your SU10 starter unit into a continuous row system. Where a starter unit requires 2 uprights to form a single bay, each add-on unit adds a full bay using only 1 shared upright — eliminating redundant framing, reducing cost per bay, and maximizing your floor footprint.

Ships complete with 1 upright, 6 straight arms, and a brace set — everything needed to attach directly to an existing SU10 bay. Arms adjust on 3" centers the full height of the upright.

What's Included

• 1 upright (10' height, 49" base length)
• 6 straight arms (36" length, 1,200 lb capacity each)
• 1 brace set (6" brace set)
• All hardware for assembly

Why expand with the AU10

Lower cost per bay than a second starter — Add-on units share one upright with the adjacent bay instead of requiring two. You get the same storage bay at a fraction of the full starter price.

Same arm capacity, same system — The AU10 uses identical Series 4000 arms and hardware as the SU10. No compatibility concerns, no mixed components — everything integrates directly.

Build as long as you need — Chain multiple AU10 units together to create a continuous row of any length. Each unit adds one full bay of storage at 10' tall with 36" arms.

Forklift accessible — Open base design allows loading and unloading directly from the aisle, same as the starter unit.

Floor Anchors (Required, Not Included): The add-on upright 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 Single-sided Add-On Units — Model Comparison

Arm capacity decreases at greater heights and arm lengths due to increased bending load on the upright column — a standard cantilever rack engineering characteristic. All capacities are per MECO Omaha specifications based on evenly distributed loads.

Need double-sided storage? See the ADU8, ADU10, ADU12 double-sided add-on units.

Specifications

Important: Capacities are based on evenly distributed loads. Arms must never be placed on the back side of a single-sided upright. Unit must be anchored to the floor per assembly instructions. Add-on units must only be used with a compatible SU10 starter unit.

Customization & Accessories

Arm Lips

Bolt-on 2" arm lips are available for this model. Lips extend 2" above the arm surface and retain cylindrical loads — pipe, tubing, round bar — that may otherwise roll off the end of the arm. Non-structural; a retention feature only.

To order with arm lips, contact us at support@mywarehouseworld.com or (929) 577-4339.

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 to a decked system for storing boxes, cartons, or furniture. Pre-engineered to accommodate 2×4 cross supports.

Custom Colors — Available at additional cost.
