"Acme" Cast Iron Mortise Shutter Hinges - 5 1/2" x 3 1/8"

This set of Victorian-style Acme Cast-Iron Mortise Shutter Hinges (5 1/2-Inch x 3 1/8-Inch) is used in applications when enough wood trim is exposed within the window opening to mount the shutters. Unlike surface mounted straps, they are mortised into the edge of the shutter and the inside edge of the window frame (much like an interior door hinge). Mass produced by Lull & Porter in the mid-nineteenth century, the Acme hinge features a patented locking pintle design where the outer leaf rises slightly when opening then sets down to lock in place in the fully open or shut position, preventing lift-off from strong winds. When needed, the shutters are easily lifted off by hand without removing the hardware. Made of raw, cast iron, they must be primed and painted to prevent rusting. The set includes two right-hand hinges, two left-hand hinges and two sill-mounted fasteners - enough to complete one window. Screws are not included.

For best performance and to prevent rust, iron and steel hardware should be regularly maintained. After installation check for scratches or chips in the surface and re-coat periodically as needed.
