Black Keyed Push Button Latch
The National Manufacturing Co. N178-418 is a black keyed push button latch designed for wood or metal screen and storm doors. It features a straight handle and a 1-3/4 inch hole spacing. The unit includes a key operated locking mechanism with two keys provided. A one piece shaft delivers firm push button action and an anti lockout design.
Verify Door Thickness and Fasteners
Before ordering, confirm the door thickness falls between 1-1/4 inch and 2 inch. The latch requires pan head machine screws sized 8-32 x 2-3/8 inch which are not supplied with the hardware. Ensure the existing bore holes match the 1-3/4 inch centre to centre spacing for proper alignment.
Suits Standard Screen and Storm Doors
This latch suits homeowners replacing hardware on standard thickness screen or storm doors where keyed entry and deadbolt security are required. Buyers needing hardware for thicker entry doors or a different hole spacing should look at alternative latch models. Those preferring a curved handle style will need a different design.

Questions about this item
Does the N178-418 latch come with mounting screws or must I buy them separately?
The latch ships with a 1-piece shaft, 2 keys and the inside latch mechanism; 8-32 x 2-3/8" pan-head machine screws are not included and must be purchased separately.
How do I know the N178-418 will fit my screen or storm door?
It fits wood or metal doors 1-1/4" to 2" thick with a 1-3/4" hole spacing; measure your door thickness and existing hole centres before ordering.
What does the anti-lockout design on the N178-418 actually prevent?
The inside latch uses an exclusive double-lock deadbolt that stops the push button from being locked from the outside while you are still inside.
