Frequently Asked Questions

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.

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.

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.

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.
