This deluxe storm door hardware set includes an elegant lever handle, interior latch, and keyed deadbolt It is compatible with most pre-installed handles, and compliments a wide range of décor styles. 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 provides additional security, so you can keep your main door open and enjoy the light and fresh air while still feel safe (this is not a high security lock, but a secondary level of security). The long-lasting finish will provide an added touch of class to any storm door. Installation This set includes everything needed for an easy 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.
