Works great in my tool chest
Classic look and feel for traditional work. Smooth turning action. Comes with all the screws and keyhole trim.

Very nice. A template for locating the keyhole would help.

Excellent working lock and well built. Only complaint is the nails for the key plate are a touch long when lock is installed in wood less than one inch thick. Easily fixed with short brass screws or a predrill and snipped nails.

Woodworking Experience:
First project requiring a full mortise
I bought the full mortise lock for a treasure chest I made as a Christmas gift for my wife. The challenge, of course, was how to machine the full mortise using my crude woodworking tools. The lock's flange plate is little over 1/4" wide by about 1/16" thick. I set my router fence a little off center of the board, with the fence a shade toward cutter. I used a 1/4" straight cutter and made two passes, flipping the board in between passes. Two stops clamped to the fence determined the length of the cut. I highly recommend using a couple of test pieces until you are confident in your setup.

The lock's mortise was a real challenge, working in oak with only a Chinese drill press. I first selected a brad point bit slightly larger than the thickness of the lock. then I marked centers equal to the diameter of the bit, along the centerline of the previous mortise.

I set the drill press table to 90 degrees (vertical) and adjusted the position of the table to the center of the first mark. I then set the stop to the depth of the mortise and hoped for the best. i used a sharp chisel to clean up the mortise,

To my surprise and delight, the lock fit perfectly!

The "latch plate" Was a different story. My plan was the same as for the 1/16" mortise for the lock. I measured and marked and marked and measured and setup the router for the cut. The mortise for the latch plate was perfect! I used the same technique as before for the clearance for the latch using the drill press and chisel.

Once assembled I tested to latch and found it didn't catch in the latch plate. As it turned out I moved the latch plate twice before I got the latch to catch in the latch plate. That's why God made wood putty and paint - to make us the carpenters we ain't.

My advice for the first timer is to actuate the lock with the latch plate sitting on top, until you understand the motion of the latch and then locate the latch plate. In spite of my mistakes, the result is beautiful and my wife loves it!

I have used this in the past. Great little lock for small boxes. I was able to pirate/adapt the quadrant hinge jigs for easy installation. Buy the deep router bit and take your time.

I like the clean look of these for large chests. They aren't the best for security but serve the purpose.

Are the keys for this lock universal? If I order several locks will the keys be interchangeable?
ArcNYC on Jan 5, 2016
BEST ANSWER: Yes, each lock is the same. One key fits them all.
What screw size does this latch use?
A shopper on Jun 11, 2015
BEST ANSWER: Mine came with screws and I have put them in place, so I'm not sure what size they were. They are brass, so I had to be careful to make the whole large enough, that the screw didn't break off. I had one break off!
What is the backset for this?
Debbie on Jun 27, 2017
BEST ANSWER: Just about anything will be ok. I centered the lock set in 5/8 thick cherry stock. I would go thicker in softer wood. I was very happy with this lock.
What are the dimensions of the latch & plate? can it be installed in 2/4" thick wood?
Mel K on Sep 16, 2015
