Place string lines on either side of the Drive Foundation and run the lines
across the roadway to determine the Receiver stanchion’s location. Keep the
string lines parallel and accurately measure the clear opening length. This
length is the distance between the inside (side facing the road) faces of the
Drive stanchion and the Receiver stanchion.

Adjust the Receiver mounting bolts and supplied templates by measuring
between the anchor bolts and ensure both sides are positioned correctly per
