Prime-Line SE 27580 2-1/2 in. Backset, Entrance Mortise Lockset, Wrought Solid Brass, Right Handed (Single Pack)

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.

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.

This was a perfect replacement for a Marks model 90 rhr mortise lock. I ordered a lhr because that’s what’s it “should” be based on the operation of the door. But really it was a rhr flipped upside down. Switching the inside mechanism was very easy. Just proceed slowly and be observant on the lay out of the guts before removing. The instructions offer pretty clear step by step. The one thing I did change was the locking bar. I made It so the handle can be used from either side not just the inside. It’s not a security door so this is ideal for my situation. All in all it was a breeze to switch around and install. Under 30 min including removal of old and changing operations and install. Bought this one used and it is in perfect working condition. Saved about $70!

This lock set serves its purpose, but I'm only giving it 3 stars because there were pieces missing. It was missing one of the #8-32 x 1.5" Phillips Pan Head screws for the door knob rosette. And the holes for these screws were too wide (I'm not sure if that was intentional or not). It was missing the plastic strike dust box that goes in the door jamb. Also, one of the cylinder rosettes was damaged (looks like it was dropped and flattened on one side). For security reasons, i needed to get this installed and in use, so I didn't have the luxury of time to return, so I found another screw from an old door knob and reshaped the rosette as much as I could (and used that on the inside of the door). It's functional and secure, as designed.

Easy to install. Unfortunately, I did not realize this is key in key out so I am currently looking for a thumbturn

Lock stopped working after a week

I was trying to find someone that could come and put a lock on my old door until I searched and found the Segal lock. This lock fit perfectly. And now my door looks so much better.

The lock is somewhat reversible upside down, wish price could’ve be a bit lower
