✅ Starter Unit vs. Add-On Unit: What’s the Difference?

When building your Jarke Button-On Cantilever Rack System with Material Flow, understanding the roles of starter units and add-on units is key to designing an efficient, scalable warehouse racking solution.

What is a Starter Unit?

A starter unit is a standalone, complete cantilever rack that includes:

• Two upright columns

• A brace set (horizontal support connecting the columns)

• Button-on cantilever arms (ordered separately or bundled)

Use a starter unit when:

• You're setting up the first section of a rack system

• You want a standalone rack

• You're storing materials like lumber, pipes, tubing, or bar stock in a single bay

Starter units are the foundation of any modular cantilever system. They’re forklift-loadable, structurally independent, and support up to 12,000 lbs. per column.

What is an Add-On Unit?

An add-on unit is a modular extension designed to connect to a starter unit and expand your system. It includes:

• One upright column

• A shared brace set (connects to the starter or another add-on)

• Cantilever arms (typically matched to the starter)

Use an add-on unit when:

• You want to expand storage capacity

• You're creating a multi-bay run of racking

• You need a cost-effective solution to grow your layout

Add-ons let you scale horizontally, maximizing warehouse space while maintaining structural integrity.
