Standards & Finishes > Standard
While we can make any hinge or pintle
of any give dimension and parameters, we can’t stock everything. So we’ve
come up with standard dimensions for lengths, standoffs and throw. These dimensions
are based on real-world examples and work in most cases. Our stock hardware
is inventoried within these parameters.
Pintle standoff is measured from the base of the pintle (where it meets
the mounting surface) to the centerline of the pin (or female cavity). We
generally stock 1”, 1 ½”, 2” and 3” standoffs.
Other dimensions are available, but carry an up charge.
Hinge standoff is measured from the back of the hinge (as it would lay
on the shutter) to the centerline of the hinge barrel. We offer hinge standoffs
of 0” (flush), 1”, 2” and 3”. If we have to jiggle
standoffs between hinge and pintle we usually go after the hinge – much
easier to vary the hinge standoff than the pintles’.
Throw is the measurement of the horizontal movement of the shutter from
closed to open. The throw is one half built into the hinge and one half derived
from pintle location. Our standard throw is 1 ½”. That is, the
centerline of the hinge barrel is 1 ½” from the offset bend
in the hinge. This dimension is based on a standard case width of 3”.
With the pintle centered on a 3” case, the hinge must span the 1 ½” to
properly mate with the pintle pin while the shutter seats within the window.
With this configuration, the full 3” of the casing would be
exposed with the shutter in either the open or closed position. One inch
of a four inch wide case would be covered when the shutter was open and the
throw was set at 3”
Strap hinge length is measured as that portion of the hinge that actually
lays on the shutter or door. With an offset shutter hinge, for example, we
consider the length of the hinge the distance from the edge of the shutter
where the hinge mounts to the end of the hinge. The hinge offset bend generally
falls on the edge of the shutter, so the hinge length is from the bend to
the end. If you have a zero offset
Hole placement. All of the weight of the shutter is born between the pintle
pin and the first fastener on the hinge. We position our first hinge fastener
hole 1 ¼” from the hinge offset bend. The first fastener then
would fall on the mid-line of a 2 ½” stile (which seems most
common). There’s nothing structural about it (as long as the fastener
hole falls on the shutter), but it looks best when the fastener is centered
on the vertical stile. All of our strap hinge fastener holes are 9/32” to
accommodate finish inside the holes plus a ¼” diameter fastener.
