Yale V80 80 Standard Dead Latch Bolt

This Yale Security V80 80 Standard Dead Latch Bolt is a night latch designed for residential entry doors. It suits homeowners replacing an existing rim cylinder lock or fitting a new door with a 2-3/8 inch backset. The lock operates by key outside and thumb turn inside. It is not for doors thicker than 2-1/4 inches or thinner than 1-1/4 inches, nor for buyers needing a mortise lock body.

1109E rim cylinder and slide button control

The lock comes furnished standard with a 5-pin rim cylinder 1109E and two keys. A slide button on the inside controls the deadlocking action and holds the latch bolt retracted. When engaged, the button renders the lock inoperable by key or knob from either side. The reversible latchbolt has a 17/32 inch throw and a 1/2 inch springbolt length. The strike is an RB8 model with an enameled Brasslux case finish.

Fits 1-1/4 to 2-1/4 inch door thickness

Installation suits doors between 32 mm and 57 mm thick with a 60 mm backset. The zinc alloy body and sprayed bronze finish mount on the door surface. Common issues include misaligning the reversible latchbolt during handing changes or positioning the strike plate incorrectly for the 17/32 inch throw. Ensure the cylinder tailpiece engages the thumb turn smoothly before tightening all screws.

Questions about this item

Does the 13 mm springbolt or the 1109E cylinder need periodic lubrication?

The 13 mm springbolt and 1109E cylinder benefit from occasional graphite lubrication; no scheduled replacement is required for either component.

What stops the latch from retracting smoothly after many cycles?

The 17/32" throw and zinc-alloy springbolt are the wear points; grit in the 13 mm bolt channel is the first limit under heavy daily use.

How warm does the 1109E cylinder get when the door is locked and unlocked all day?

The brass 1109E cylinder and zinc-alloy body stay at ambient temperature; no measurable heat rise occurs during continuous operation.
