UKSF Box Section Cross Member Beams for Rigs and Racks

UKSF box section cross member beams are built to add strength, stability and versatility to your rig and rack layouts. Manufactured from 75 x 75 x 3mm steel box section and reinforced with signature UKSF gussets, these beams are designed to connect structures together while reducing movement across the frame.

Available in 1080mm and 1800mm lengths, they are ideal for linking rigs, joining power racks, and creating solid upper framework when using UKSF rig leg extenders.

Designed to Connect Rigs, Racks and Training Structures

These cross members allow you to securely connect multiple uprights and structures to create a more rigid and unified training frame.

  • Join separate rigs or racks together

  • Extend existing rig layouts without compromising stability

  • Create continuous pull up or attachment spans across bays

  • Increase overall frame rigidity in high-use facilities

Perfect for CrossFit, functional fitness and strength & conditioning gyms where rigs are under constant load.

Essential When Using UKSF Rig Leg Extenders

When uprights are increased in height using UKSF leg extenders, adding a cross member beam across the top is strongly recommended to stabilise the structure.

  • Reduces sway at increased heights

  • Reinforces the top of extended uprights

  • Maintains rigidity during kipping, muscle ups and rope work

  • Creates a stronger, safer training frame

Compatible with Ring and Rope Mount Attachments

These beams also act as the ideal mounting point for UKSF ring and rope attachments, allowing you to expand the functionality of your rig.

  • Secure fixing point for rope climbs

  • Stable anchor for gymnastic rings

  • Ideal for creating dedicated gymnastics and rope stations

  • Allows multiple training functions from the same structure
