Prime-Line U 9970 Deadlock – Jimmy-Resistant Design Prohibits Forced Entry by Spreading of Door Frames – Single Cylinder Diecast Metal Lock With a Brass Finish and Angle Strike (Single Pack)

Very solid easy to install lock. Heavy duty this was easy to install, it fit the doorframe perfectly and it functions as it should. Great lock, great price!

Awesome lock! I feel so safe.

Good quality

This replaced a stainless steel Segal lock that looked same as this one. The four long screws went over the old Segal at exactly the same positions, but the height of this new lock is a little shorter than the old one, so there is a little space between the door and the base of this lock. It is not a perfect fit but I use this lock for added security only, I do not use the keys that came with it, as this door has another main lock with key. I also had to use my old strike plate or called latch?, because the strike plate/latch that came with this lock is a 90 degree L-shaped one that does not fit over my door frame/molding which angles inward, not 90 degrees. Make sure to ask for the proper strike plate/latch before ordering. So, I have a brass colored lock with a steel colored receiving end latch; alittle funny looking but I don't want to bother with the return right now because the lock works just fine. I wish they had advertise which strike plate they were selling to begin with though, otherwise the lock is very good, smooth, quiet and very affordable.

Replaced an old, same style, one side keyed lock with inside knob lock on a door with upper glass. Easy to install, great instructions.

I had a need to pass local home inspection and my 35+ year old double cylinder lock wouldn't pass. So, I bought this with the hope I could just replace the inside piece and leave the other older existing parts installed. Got the lock, unscrewed four screws that hold the lock in place and viola, it fit perfectly! Old key and strike mechanism were fine to work with the new inside lock that now has a code compliant knob to lock and unlock the door. Couldn't be happier!

Muy buen producto lo recomiendo

It wasn't the heavy duty old school brass I thought I was getting. Lost the key to my top lock & decided to replace it. This model was slightly smaller & didn't fit. But also felt "more hollow" than my original. I decided to just replace the key entry & tumbler by placing it in my older top lock. Worked out for me after doing a little McGuyver touch to it.

quick shipping , very well made no nonsense lock

Good solid lock, easy to understand instructions.

extra lock for back door, easy to fit for a person who has basic diy skills
