Lightweight, strong, speedy adjustment and meets NZ code requirements.

 Suitable for positioning & stabilising precast and timber columns, precast wall panels, blockwork walls, and formwork.

Panel Props should be positioned between 60% and 85% up the face of the panel from finished floor level.

NOTE:
Values in this table were calculated considering a 0.5kPa wind loading applied to the panel and gravity loads imposed on the prop in compression due to a 5 degree inclination angle to the vertical. It includes a factor of safety of 1.5. 

Factors for earthquake loadings producing lateral accelerations of > 1/3G may be calculated using the following formula:
Earthquake Prop Spacing = (Prop Spacing from table) ÷ (C × 6).
Where C = Earthquake coefficient from NZS 4203:1992.

A similar equation can be used for higher wind pressures than 0.5kPa.
 High Wind Prop Spacing = (Prop Spacing from table x 0.5kPa) ÷ (Local Wind Pressure (kPa))
