Everything you need to get started
Our lightweight construction, attached hardware, and simple-to-set forms cannot be beaten for speed and efficiency.
8' 4 Bar System Overview
the 4-bar system was designed when panels were stacked flat on trucks and moved by hand around the jobsite. Light weight was key and reducing the number of bars on a form mean it was easier to move around by hand.
4 bar System Limitations
The 4-bar system has some limitations due to the tie spacing. Spacing between ties is 20" - 24" - 24" and 20" to the top of the form. Special consideration is needed when stacking, pumping or vibrating due to "push" or deflection between bars. Contractors need to follow pour rate of 4ft/hour to ensure safe pouring conditions.
Compatible Forms
The 4-bar system will line up with 4' 2 bar, 6' 3 bar, 9' 5 bar, 10' 6 bar and can use 2' 2 bar stackers.
