The 5 Series is BLK BOX's commercial-grade rig and rack range, built for facilities training high volumes of members or athletes where equipment durability under constant use matters more than anywhere else in a facility. It's the range trusted by Premier League clubs and institutions including Loughborough University.
Constructed from 80x80x3mm steel, the thickest gauge across BLK BOX's rack ranges, and backed by a lifetime guarantee, the 5 Series is built for facilities where equipment failure isn't an option. Textured grip pull-up bars, Westside hole spacing, and height options of 2.3m or 2.5m give it the specification demanded by elite training environments.
Available in a range of colours with bespoke custom branding options, the 5 Series also suits facilities wanting their equipment to reflect their own brand identity rather than a generic gym aesthetic.
