They break to a sloped face that goes up to 13 inches over the sidewalk on the Jersey barrier, but only up to an elevation of 10 inches in the instance of the F-Shape.


The Texas Constant-Slope Obstacle is 1070 mm (42 in) high and has a constant-slope face that makes an angle of 10. 8 degrees relative to the upright. California developed a Solitary Slope account that makes an angle of 9. 1 degrees with respect to the upright (Crash Beams).
