Stepped piers work better for steel barred gates.
Boarded gates leave an unsightly gap. Filling the
gap is likely to cause a pinch hazard.
Rear hung gates, where the casement is on the
back of the pier (Fig 1c) eliminate the sight gap,
and can hide the necessary safety edge.
However on turning the casement the adjustable
closed stop no longer works. You will need a
centre stop or an alternative casement stop.
The top hinge on a boarded gate is critical to
quality installation. Top hinges need to be plumb
above the casement pivot. Fig 3 gives some
alternatives.
The most common
[D]
requires the gate to be
off centre, and therefore will require a safety
edge to protect the pinch hazard.
[E]
is on centre, but leaves a sight gap, or you
need to cope with a rear hung gate.
[F]
is ideal, but needs a special hinge fitting to
the top of the gate.
Be sure to discuss top hinge design with your
gate supplier. The design will affect safety, pier
design, the gate’s dimensions, opening angle and
entrance width.

Gate mounting
[A]
is frequently requested, but requires extra safety edges
because of the crush risk between the gate and the pier.
[B]
recommended for safety and has a good opening angle.
[C]
casement must be turned through 90° and mounted on
the back face of pier. This results in a reduced opening angle.
