Marsh Products 18x54 PVC-Encased Inductive Vehicle Detection Loop

so here's how I do my loops I'm using a BT loops preform saw cut this is a six by eight loop we're gonna cut here so I start by making some general measurements to where you want it start with your layout this is triangle number one you can see they're numbered but sprayed over them a few times so that's your yolk corner they move to number two where you just measure out your the long leg which in this case was eight feet stretch it out put it in there see the loop fits right in number three is the corner and there's a little red mark here that you put into right-center that's the like dead middle of your loop then you measure your long short leg I squared it up measured ten feet each corner so now I'm gonna chalk line all around that and then spray it with clear inverted marking paint which is this stuff and what that does is that just keeps the chalk line in AU shape that in a minute
