Silver Keyed Push Button Latch

The National Manufacturing Co. N178-426 latch fits wood or metal screen and storm doors with 1-3/4 inch hole spacing. A straight handle operates a key-operated locking unit supplied with two keys. The mechanism suits doors from 1-1/4 to 2 inches thick and uses an anti-lockout design for safety.

Installers fitting standard screen or storm doors

This latch matches the common 1-3/4 inch spacing and 1-1/4 to 2 inch door thickness range. Builders working with non-standard hole patterns, heavier entry doors, or electronic access systems will need different hardware.

1-3/4 inch hole spacing

The 1-3/4 inch centre-to-centre measurement is the single dimension that determines whether this latch aligns with existing door preparation. Verify this spacing before purchase; other spacings require a different model.

Questions about this item

How do I install the N178-426 latch and what screw size is required?

Mount the latch on wood or metal screen and storm doors 1-1/4" to 2" thick using 1-3/4" hole spacing. You must supply 8-32 x 2-3/8" pan head machine screws as they are not included.

What maintenance or replacement will the keyed locking unit need over time?

The lock cylinder may eventually require re-keying or lubrication if the key action stiffens. The 1-piece shaft and push-button mechanism are built for durability, but the two supplied keys should be kept safe as replacements are model-specific.

What is the first limitation I will hit during heavy daily use of the push-button action?

The 1-piece shaft provides firm push-button operation, but the 8-32 mounting screws bear the mechanical load; if they loosen in wood or metal, the latch alignment will shift before the internal mechanism fails.
