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.
