Yale 378LN Deadlatch Kit Grade 2

The Yale 378LN is a Grade 2 deadlatch kit finished in satin chrome. It suits standard-duty locksets on interior or exterior doors. The kit fits doors from 1-3/8 in to 1-3/4 in thick. It is intended for residential or light-commercial use where a fire-rated latch is required.

2-3/8 in Backset Constraint

The latch operates on a fixed 2-3/8 in backset. Doors prepared for a different backset cannot accept this kit without re-boring. The fire rating covers three hours on labelled assemblies. No adjustment for alternative backsets or door thicknesses outside the stated range is provided.

Grade 2 Fire-Rated Security

The single specification that decides fit is the Grade 2 fire-rated certification for three hours. Buyers needing a non-rated latch or a higher-grade heavy-duty unit should select a different product. This kit meets the requirement where codes demand a Grade 2 three-hour latch.

Questions about this item

Should I choose the 2-3/8" backset or a different size for my door?

This kit is built for a 2-3/8" backset only. Measure from the door edge to the centre of the existing bore hole; if it matches 2-3/8", this is the correct version.

What does the Grade 2 rating mean once the latch is installed?

Grade 2 indicates the latch meets commercial-grade cycle and strength tests, so it withstands heavier daily use than residential-grade hardware.

How does the 3-hour fire rating affect what the latch can do?

The latch is tested to maintain integrity for three hours in a fire-rated door assembly, allowing it to be used on labelled fire doors without compromising the rating.
