DF4 - Lightning Bolt 2-piece Closure

     This two-piece Closure Bolt is our fastest closure. It is for only 2-3/8" backset doors with jambs up to 1" thick, right or left hand swing. It can be used on interior doors and exterior door to eliminate sag and to secure the door from manufacturing through installation. 

     The DF4 Closure requires a 1" diameter or a 3/4"x1" rectangular hole through the jamb. The two parts are supplied in a connected set for a quick grab out of the box and ensure an equal number of matching parts are supplied in each box.
