BLK BOX Samson/5 Series Pivot Attachment

An extremely versatile piece of kit. The Pivot attachment is in pristine condition. Sells for €597 new if bought directly from BLK BOX.

BLK BOX retired the Samson series rack but the 5 Series rack is the direct successor to the Samson series and is fully compatible with Samson series attachments.

To ensure compatibility if you don't own a BLK BOX Samson/5 Series rack, your rack needs to have:

Upright size: 80 × 80 × 3 mm steel
Hole spacing: 75mm
Hole diameter: ~21mm (as the pin diameter for the Pivot attachment is ~20mm)

The Pivot attachment is a must-have for athletes looking to up their strength game in unprecedented ways. Easy to attach and adjust on Samson/5 Series racks, the Pivot is attached on to the rack using two hitch pins, the top one acts as a pivot and the bottom one acts as a selector pin for the various adjustable positions.

The Pivot has 5 working positions ranging from 10°, 30°, 50°, 70° and 90° (Horizontal) off the vertical upright. These adjustments can support the head, back, arms, legs, or feet for that extra stability needed during multiple movements.
