Calculating gate width with existing pillars or posts in place.
Take THREE measurements between the pillars/ posts. Across the top, middle and bottom. Make a note of the SMALLEST measurement.
Gates to open towards driveway. Hinge plates mounted to rear face of post/ pillar. Back edge of gate sits flush with the back edge of post/ pillar.
REDUCE 50mm (2″) from your lowest measurement.
Gates can open both ways. Hinge plates mounted to inner face of post/ pillar. Gate to be mounted central between the posts.
REDUCE 150mm (approx. 6″) from your lowest measurement.
If adding underground automation, reduce width by 110mm.
