MECO Series 1000 Cantilever Rack Straight Arms

MECO Series 1,000 Straight Cantilever Arms

These straight cantilever arms are the load-bearing components that attach to Series 1000 uprights and form the actual storage surface. Arms adjust on 3" centers up and down the upright column using a hairpin keeper, allowing you to reconfigure storage levels without tools as inventory needs change. Straight arms include a minimum pitch of 3/8" per foot to compensate for deflection under load, keeping the arm level in use rather than visibly sagging. A retaining lip option is available for load containment.

Seven lengths are available from 12" to 48". Capacity per arm decreases as arm length increases because longer reach increases the moment load on the upright. Select the arm length that fully supports the load width, then verify the per-arm capacity covers the weight of material on each arm at each storage level.

Note: Compatible with Series 1000 uprights measuring 3" wide x 6-1/4" deep.

Choosing the Right Arm Length and Capacity:

♦ MSA12: 12" long, 1,000 lb per arm. The shortest and highest-capacity arm in the series. For compact layouts with narrow loads.
♦ MSA18: 18" long, 750 lb per arm. Added reach for slightly wider materials without a significant reduction in capacity.
♦ MSA24: 24" long, 600 lb per arm. A common choice for pipe, conduit, bar stock, and similar mid-width materials.
♦ MSA30: 30" long, 500 lb per arm. For materials requiring deeper reach, such as wider lumber or extrusions.
♦ MSA36: 36" long, 400 lb per arm. Suited to wide sheets, long boards, or bulk material stored at a shallower depth per level.
♦ MSA42: 42" long, 350 lb per arm. Extended reach for the widest materials in the series.
♦ MSA48: 48" long, 300 lb per arm. The longest arm available. Lowest per-arm capacity: verify that load weight per arm does not exceed 300 lbs at this length.

The arm length must also match the selected upright base length. Confirm compatibility with your upright base length before ordering. See the upright pages for base-to-arm length compatibility charts.

Note: Compatible with Series 1000 uprights measuring 3" wide x 6-1/4" deep.

Where Series 1000 Straight Arms Are Commonly Used:

♦ Lumber and sheet goods: Supporting dimensional lumber, plywood, OSB, and panel products at organized storage levels accessible from the front without front column interference.
♦ Pipe, conduit, and tubing: Storing bundles or individual lengths of round material on straight arms -- use a retaining lip when storing round or rolling materials to prevent forward movement.
♦ Bar stock and structural steel: Organizing flat bar, angle iron, or light structural sections at assigned rack positions by size and grade for faster retrieval.
♦ Cartons and stable unitized loads: Storing boxed or banded loads on straight arms where the load is stable and front containment is not required.

Frequently Asked Questions (FAQs)

What is MECO Series 1,000 medium duty cantilever racking used for?

MECO Series 1,000 medium-duty cantilever racking stores long, bulky materials without front columns blocking access. It helps your facility organize items that are hard to place on a standard pallet rack. Typical uses include lumber, tubing bundles, trim, bar stock, panels, and other hand-loaded materials. The open-face design gives workers clear access to each storage level. This helps improve storage density while keeping materials easier to see and reach.

How do I purchase MECO Series 1000 cantilever straight arms?

Start by confirming that your existing rack is MECO Series 1000. Series 1000 arms, uprights, and brace sets are compatible only with Series 1000 components. They are not interchangeable with any other MECO rack series. Choose the arm length, capacity, and lip style based on the material being stored. Also, confirm how many arms each level needs to support the load safely.

Should I choose straight arms with or without a retaining lip?

Straight arms without a retaining lip allow easier loading and unloading from the front. They work well for stable materials that do not slide or roll during handling. Straight arms with a retaining lip help keep materials from moving off the arm edge. The lip adds front-end retention, but it does not increase the arm capacity. Choose the style based on load movement, handling method, and facility safety needs.

What common questions do buyers ask about MECO Series 1000 cantilever racking?

Buyers often ask if Series 1000 arms fit other MECO racks. They do not, because Series 1000 components are only compatible with the same series. Many also ask whether a retaining lip is required for every application. A lip is useful when material may shift, but stable loads may not need it. Buyers also ask about capacity, arm spacing, and whether they need new brace sets.
