C.R. LAURENCE DL2240A CRL Header Bolt Kit for 30-1/2" to 50" Cylinder Centerline to Top of Door
The CRL DL2240 Series Header Bolt Sets are designed to add a top-of-door third locking point for pairs of doors with a DL2110 Deadlock and a DL2230 Series Threshold Bolt Kit in the active leaf. The DL2240 Series Header Bolt is mounted in the inactive leaf. This additional bolt, triggered by the Deadlock Throw bolt, expands in a "scissors" action to center itself in its strike as it rises. This action saves the key holder from the difficulty of lining up the doors with three separate strikes.
