Frequently Asked Questions

What makes the 3 Series different from the 1 or 5 Series?

The 3 Series offers a modular, future-proof design using 70x70x3mm steel. It includes 4-way numbered hole spacing and a broader range of colour and branding options than the 1 Series, while remaining more accessible than the elite-level 5 Series.

What are the height options for the 3 Series racks?

Racks are available in 2.2m or 2.4m heights to suit different ceiling clearances and facility needs. Taller options (up to 3.6m) are also available for rig setups.

Can I integrate cables and storage into the 3 Series?

Yes - the 3 Series supports integrated cable columns and multiple storage attachments. It’s designed to reduce footprint while enhancing training versatility.

Is the 3 Series available in different colours?

Absolutely. The 3 Series comes in 14 standard colours with optional branding upgrades, including custom brand plates and stack guards.

What are the key differences between the 1, 3, and 5 Series?
  • 1 Series: Entry-level rigs and racks made from 60x60x3mm steel, designed for quick installation and rapid delivery.
  • 3 Series: Modular and expandable, made from 70x70x3mm steel. Ideal if you’re looking for scalability and attachment compatibility.
  • 5 Series: Premium and fully customisable, made from 80x80x3mm steel. Includes Westside hole spacing and advanced performance testing attachments.
