About this item

Product details

The Member's Mark 5-Tier Heavy-Duty Interlocking Plastic Shelf is a tough, modular storage solution that adds organized, easy-to-reach space in garages, pantries, utility rooms, closets, and more.

Heavy-duty storage, built to organize

With five ventilated, extra-sturdy shelves, this unit keeps everyday essentials visible and accessible while helping reduce clutter. The shelves are non-adjustable with a fixed 14.625" spacing between each shelf.

  • Each shelf supports up to 200 lbs. when weight is evenly distributed.
  • The unit supports up to 1,000 lbs. total when weight is evenly distributed across all shelves.
  • The 48" W x 20" D shelf size is ideal for organizing items like canned food, cleaning supplies, tools, hardware, and storage totes.
  • The assembled footprint is 48" W x 20" D, with a 72" H vertical design that adds storage without taking up extra floor space.

Easy-clean resin that resists everyday wear

This heavy-duty shelving unit is made from easy-to-clean recycled black resin material designed to resist rust, dents, stains, and peeling. At 36.8 lbs. per unit, it is lightweight enough to move from room to room as your storage needs change.

Modular interlocking system for flexible layouts

The interconnectable modular system allows multiple shelves to be linked together to expand your setup. Shelves can be interlocked side by side for a wider configuration or connected front to back for deeper shelving. One unit can also be reconfigured into two shorter shelving units by stacking a 3-tier shelf and a 2-tier shelf.

Stability on uneven floors

Adjustable leveling feet are included to help keep the shelving unit stable and secure on slightly uneven floors or ground.

Pairs with Member's Mark storage totes

The Member's Mark 5-Tier Heavy-Duty 20" x 48" Shelf is designed to pair in both color and size with the Member's Mark 27 Gallon Heavy-Duty Storage Tote to help streamline the organization and look of home or workspace storage.

Assembly and best-performance guidance

Assembly is designed to be tool-free and can be completed by one person; however, it may be necessary to use a mallet or small hammer to gently tap each post into place. Assembly instructions are on the back of the product label and in the product images above.

  • For maximum shelf strength, distribute weight evenly and place the heaviest items on the lowest shelves.
  • For every 5°F above 95°F, decrease the weight on shelves by 10%.
  • Wall mounting is required for maximum weight capacity and stability; four U-shaped wall mounting brackets are included.
  • Wall-mounting hardware is not included; use four 0.185" diameter screws long enough to secure into the wall stud, and use anchors when a wall stud is not present.

Frequently Asked Questions

Heavy-duty polypropylene/plastic (recycled black resin) that’s easy to clean and designed to resist rust, dents, stains, and peeling.

Sturdy and easy to assemble.

Very easy to put together. Holds many totes, depending on which way you put them on the shelf. I really want to replace all of my shelves in my garage with these.
