Thanks to the modular design of Rivetwell shelving, maxing out your starter shelf won't limit your ability to get organized. Add-On Units are designed with distribution in mind, sharing a common T post between units. In this way, the Add-On Unit helps to support the starter shelf, hold additional items, and keep you organized.

Each style of decking has its own benefit, make sure to pick the style that's right for you.

  • Wood decking is made of dense particle board, a heavy but affordable option
  • Wire decking can reduce your insurance premiums but is a larger investment up front.
  • Ez-Deck offers a metal platform for added strength and reliability.
  • Feather decking is made of a corrugated polymer, offering a lightweight storage option.
  • Manufacturer: Hallowell
  • Weight: 63-205lbs
