This deluxe storm door hardware set includes an elegant lever handle, interior latch, and keyed deadbolt It is compatible with most pre-installed surface mount handles, and compliments a wide range of decor styles.Please note that it does not replace any other mortise handle sets. The elegant and easy to operate handle replaces the basic push button handle that may already be on your screen door. The interior latch features an easy opening push movement. The matching keyed deadlock lock is not a high security lock, but a secondary level of security that provides additional security. The long-lasting finish will provide an added touch of class to any storm door. This set includes everything needed for installation and will fit doors from 1" to 2-1/8" thick. Installation should take about 30 minutes. When replacing an existing handle, the screw posts for the handle must be 1-3/4" apart. For new installations, three additional holes are required to be drilled through the door for the screws and spindle. The lock can be installed above or below the handle, depending on your preference. The spindle for the deadlock may be cut for your particular installation. A tape measure, drill and screw driver will be required. A center punch to mark the holes is helpful. Before drilling, ensure that the inside latch and lock do not interfere with the operation of your main door handle. If they do, raise or lower the storm door hardware.
