Frequently Asked Questions

Is the load capacity per shelf or for the entire unit?

The 600 lb figure in this listing's selected option is per shelf, not a complete-unit capacity. Confirm the applicable loading conditions and whole-unit rating for this exact configuration before purchase.

Does the load capacity vary by size?

This page has one listed size and color configuration. Other sizes are sold on separate listings and may have different ratings. Use the selected option and applicable documentation for each product rather than transferring a rating from another model.

How do I choose the right shelving size?

Use the dimensions in the selected variant title: W = width, D = depth and H = overall height. Measure the installation area, including clearance for doors, walkways and access, then compare the shelf depth and vertical space with the cartons, tools or supplies you plan to store.

What is included in the package?

The selected 4-tier rack includes the components needed for standard assembly: upright posts, beams and braces, four shelf levels or shelf panels, and the relevant slot-in or joining components. The exact component set may vary by selected size. Storage items shown in photos, assembly tools and wall-anchoring hardware are not included unless the selected variant specifically says otherwise.

What tools are required for assembly?

You will need a screwdriver to secure the upright posts with screws. Once the uprights are fixed, simply snap the horizontal beams and shelf panels into place to complete assembly; no additional screws are required for those components.

Where does this shelving ship from, and how long does delivery take?

Shipping origin, handling time and transit time depend on the selected size and color, current inventory, order quantity and delivery destination. Before ordering, send us the selected SKU or variant and your delivery ZIP/postal code so we can confirm the shipping warehouse, current handling time, freight cost and estimated delivery window.

Can I buy just one shelving unit?

Yes. Choose an available size and color, select your quantity and add it to your cart. Online prices apply to the selected configuration.

How do I get a quote for 10 or more units?

Use Request Bulk Quote and include your size, color, quantity and delivery location. You can also inquire about smaller business projects. The 10-unit guideline is an invitation to request a quote, not a minimum for online purchases.

Can I request a custom size?

Send your dimensions, load requirements and quantity. We will review the request and confirm available options, any minimum order quantity and lead time before you order.

Is assembly required?

Yes. You will need a screwdriver to secure the upright posts with screws. Once the uprights are fixed, simply snap the horizontal beams and shelf panels into place to complete assembly; no additional screws are required for those components.
