Excelsior Exterior Cast Iron Shutter Bolt 640-055

Excelsior exterior shutter bolt in cast iron patented September 1860 and April 1862.  These bolts allow shutters to remain open a small amount to allow air flow thru open windows while keeping the windows secure.  The bolt case measures 6" by 2 1/2" and the keeper measures 3 1/8" by 2 1/2"  The hole in the keeper is what allows the latch to be slightly ajar and the lever on slide allows the bolt to be locked in place.  Each bolt is as pictured, restored, working, and complete.
