Frequently Asked Questions

What is Westside hole spacing, and why is it important?

Westside hole spacing means holes are spaced 37.5mm apart in the bench/squat zone, allowing more precise J-Hook and safety arm adjustments for better ergonomics and injury prevention.

What customisation options are available for the 5 Series?

The 5 Series is fully customisable - from colour and laser-cut branding to stainless steel construction, J-Hook colour accents, and stack guards. It’s the most tailored range in the BLK BOX lineup.

Is the 5 Series suitable for performance testing?

Yes. The 5 Series integrates seamlessly with Smith Machines, Rolling Jammer Arms, IMTP testing kits, and other performance attachments - making it a go-to solution for elite sports teams and research-based institutions.

What kind of steel and hardware does the 5 Series use?

Each rack is made from 80x80x3mm steel with M20 hardware and numbered uprights. It’s designed for uncompromising strength, backed by a lifetime guarantee.
