cross-pillar measures
How do you check the dimensions between pillars when installing your gate or wicket door?
1) I check the width between pillars
Using a tape measure, measure the width between pillars at 3 different points (top, bottom and middle of your pillars).
Keep only the smallest of the 3 measurements.
2) I check the height
Measure the height of your pillars. Allow a minimum clearance of 100 mm between the underside of the pillar cap and the top of your gate (or wicket door).
For sliding gates
If you're planning to install a sliding gate, you'll also need to take into account the lateral clearance required to open your gate. This is what we call the back swing.
For Packit sliding gates, this offset must be at least equal to the width between pillars + 400mm. For added safety, you may wish to allow an additional margin of about ten centimeters.
