## Description

These double cylinder, heavy-duty entrance mortise locksets are constructed of various materials and come in a polished brass finish. They are designed for use on exterior entry doors, engineered to match the vintage hardware of interior doors, without jeopardizing the security of your home. For use on entry doors ranging from 1-3/8 inch to 1-3/4 inch thick, and with the Segal keyway lock cylinders you can enjoy the beauty of yesterday’s vintage hardware with the strength of modern day security hardware. The knobs of these locksets are constructed of diecast and reinforced steel components, and they’re finished off with a beautiful wrought, solid, polished brass finish. A gray plastic dust box is also included for installation beneath the strike plate. As an increased security feature, this lockset features a split spindle knob system designed to prevent breaching of hardware from the exterior side of the door. The spindle half with the female threading and cross pin inserts from the exterior, while the spindle half with the male threading inserts from the interior side of the door. The knobs fasten to the spindle pieces with the set screws found on each knob shaft. Although the handing's of these locksets are reversible (instructions included), there are matching locksets available with opposite handed latches ready for installation. Detailed, simple to follow installation instructions are included with each entrance mortise lockset.

Review: Lock works smoothly. Easy install. - First it’s was $89 6/25 just before prime. Now it’s $99,$139…. But it works great. We had replaced our very old locks with new ones about 7 years ago. The new ones never were that great (Marks brand). Unlike the last once, these were extremely easy to put in and work smoothly after. Just remember the 2 screws in blue plate hold the locks secure. So basically they are the most importantly part. These screws are side by side, parallel to the circular locking mechanism. Loosen to remove the cylinder and tighten to secure the cylinder (lock). The cylinder does not have to be tight in place. The screws take care of that. Just line it up where the dead bolt will lock. We had to reverse ours with name upside down to get it to work. Must have purchased the wrong handed side. Blessing.
Review: Excellent product - I searched high and low for this lock for over a month to used on a home that I am rehabbing. After buying the wrong lock several times, I found this one for an amazing price. Unfortunately, my partner also found the lock (at a much higher price) and purchased it the same day so I didn’t end in using it…. Compromise for having it on hand.

### ⭐⭐⭐⭐⭐ A lifesaver and moneysaver!!
*by D***R on November 16, 2020*

I have a 90 year old front door whose mortise lock no longer works. We couldn't enter from the front any more! But finding a replacement for it seemed almost impossible. I was quoted $1000 for a similar Baldwin lock from a specialty hardware outlet!! The Segal lock was an almost identical fit to the original, and modifying the door to accept its doorknobs was mostly straightforward. I had to switch it to a left handed lock, but the clear directions that accompanyed the lock made this a snap - very easy to do. I now have a beautifully-solid operating front door that's more secure than ever! And for an extremely low price!!! I would have been willing to pay triple what I paid for the quality of this lock. I strongly recommend this company and this lock if you should have the misfortune of replacing a 90 year old mortise lock like we had.
