CRL U9845 Wood Sash Window Security Pin

CRL Wood Window Security Pins are brass plated steel pins which lock a window in a closed or a ventilating position. A pin removal key is needed to unlock. These pins are recommended for wood sash windows. Simply drill two 5/16" (7.9 mm) holes, 2-5/8" (66.7 mm) deep while the sash is in a closed position and install pins for total security. Drill two more holes approximately 3" (76 mm) above the first set in the outer sash for security plus ventilation. Each package contains eight pins and four keys.
