The elegant and easy to operate storm door handle hardware from Idea Security replaces the standard handles pre-installed on most aluminum, wood or vinyl storm or screen doors. No more levers to turn, simply pull to get in and push to get out. The set includes an outside handle, inside latch, a key lock and deadbolt, in the same finish along with all installation accessories. The included key lock allows you to keep your main door open while keeping your storm/screen door securely shut. The interior latch doesn't lock. This set fits doors from 1-inch to 2 1/8-inches thick. If replacing an existing handle, the screw posts must be 1 3/4-inches apart. For new installations, three holes must be drilled through the door for the screws and spindle. The key lock is usually installed above the handle. The spindle for the deadlock can be cut for custom installs.
