Prop Inner Tube: 48.3mm O.D. tube (standard scaffolding tube size) with holes at 152.5mm centres. Tube diameter enables standard scaffold tube and couplers to be used for bracing purposes.
Prop Outer Tube: 60.3mm O.D. Bottom plate identical to prop head. Reduction couplers enable standard scaffold tube to be connected to outer tube for bracing purposes.
Thread: On the outer tube the thread provides the ability for each prop to have infinite adjustment within its given range.
