I am building a driveway gate which spans about 15 feet i.e. each gate will be about 7.5 feet wide. I ordered these hinges and would like to figure out the exact width of each gate. The "pivot" of the hinge (measurement C in the link) is 1/2 inch so does that mean I should subtract 1/2 inch from the width of each gate? And should I allow for a gap in the middle where the gates meet when closed?
thanks in advance! Eric
