Yale P-77 Traditional Nightlatch (60mm) Electro Nickel Brass finish – Standard security
Product description
If you’re updating a door lock and want something that feels more “traditional” than modern smart hardware, the Yale P-77 Traditional Nightlatch is a straightforward option. On paper, it’s aimed at everyday residential security, with a package that includes a rim cylinder and keys.
Below-the-surface details matter with nightlatches, and Yale’s design here includes anti-bump protection plus an internal deadlocking arrangement using the SNIB function. That combination can be a real plus if you want the latch to behave predictably, rather than leaving more to guesswork.
The essentials
This is a 60mm traditional nightlatch in an electro nickel brass finish. It’s supplied as a complete package with a rim cylinder and two keys, which makes it simpler to buy in one go rather than hunting for matching components.
The lock includes anti-bump protection. It also features a SNIB function, which lets the latch be held back. Finally, there’s internal deadlocking: the latch can be deadlocked internally using the SNIB button.
It’s the sort of lock that suits typical front doors and interior scenarios where you want nightlatch-style operation and a traditional feel, rather than switching to a different locking approach.
What you’ll notice in everyday use
The big day-to-day advantage is how it’s designed to control the latch action. With the SNIB function, you can hold the latch back, which can be convenient depending on how you use the door.
And because there’s internal deadlocking via the SNIB button, you get an extra layer of “lock it and forget it” behaviour when the time comes to secure the door. It’s not a feature set meant for constant fiddling, but it can reduce the number of times you have to think about whether the door is fully secured.
Small limitation: nightlatches can be straightforward, but they’re not the same as fully motorised or smart locking systems—so if you’re expecting remote access or app control, this won’t match that kind of requirement.
Where it shines (and where it may not)
Worth considering if you want a traditional nightlatch setup that focuses on practical security measures.
It may not suit you if you already have a door locking arrangement that requires a different backset or cylinder type. You also may want to skip it if you’re looking for something beyond basic latch-and-deadlock behaviour, because the information provided doesn’t indicate extra bells and whistles like electronic functionality.
Key takeaways for buying with confidence
Before you buy, double-check sizing and fit, especially the 60mm backset. A correct backset is one of those details that can make or break the installation—if it doesn’t match your existing door setup, you may end up needing additional parts or a different lock.
Also consider what “complete package” means for your situation. Here, the lock is supplied with a rim cylinder and two keys, which is helpful, but you should still confirm whether your door currently has compatible fixing points.
If you’re choosing between approaches, this is firmly in the traditional mechanical lock camp. For many households, that’s exactly the appeal: fewer dependencies, no batteries to manage, and a setup that’s designed for everyday use.

Is it worth it?
Buy it if you’re fitting or replacing a traditional 60mm backset nightlatch and you value the included security approach: anti-bump protection, SNIB to hold the latch back, and internal deadlocking using the SNIB button. The fact it comes as a complete package with a rim cylinder and two keys also makes it more practical for a straightforward replacement.
Don’t buy it if the door requires a different backset/cylinder arrangement, or if you’re specifically after electronic or smart locking features (the provided details point to a mechanical traditional nightlatch, not a connected system).
