LDI-LA22 "THE LONG ARM"

A cost effective solution to K-4/K-8 barriers on road ways up to 20 feet wide are barrier arms. With proper design, you get full open or close in 6-7 seconds.One type has steel below grade (where the concrete has been poured) and the other type is with the concrete on the surface.The above grade option offers less installation costs and with the use of the cement blocks, you can get a higher K rating. However, it will require a longer travel distance, as the concrete is designed to move a few feet with an impact. These do not provide any type of pedestrian control.
