There are two methods commonly used for installing Quik-Fit stirrup mats. The most common of these is to place a mat inside of the inner cage with loops directed toward the outer wall of the pipe. The mat is then securely attached to the inner cage. An alternate method is to insert the loops through the outer cage toward and through the inner cage. CAM LocRods are then inserted into the tips of the loops which extend through the inner cage. This method is preferred when stirrups are required for small to medium diameter pipe when it is difficult to install the mats from inside the inside cage. Box culverts and three sided structures often require shear reinforcement on both cages for top,bottom and side walls. The Quik-Fit system provides shear reinforcement to both cages as well as, securely tying the cages together. Please refer to the pictures on this page and the following one.
