    • Quick and painless fix
Color: Bronze Size: 2-1/4 in.
Great price and I didn't have to change the whole mechanism, just the inner and outer door knob.

    • Historic Home
Color: Bronze Size: 2-1/4 in.
Excellent product for 1874 built home. Only problem is old setback mechanism stripped except one way. The axle included was just a hair too small to catch and move the latch lip. Found one setting for original stripped axle to work and reused it. Lock and catch like new now. Hope this helps someone.

    • Great simple\cheap fix
Color: Bronze Size: 2-1/4 in.
Excellent simple cheap fix. Install took less then 10 minutes and now I can open the kitchen pantry closet with a doorknob instead of having to use a butterknife Smiles.

    • Does what it is supposed to.
Color: Bronze Size: 2-1/4 in.
The old house I bought 25 yrs ago had a door in the basement with no doorknob. I don’t know why I never got around to putting one on for so many years, but finally I did and it works great.

This was a very easy DIY repair! I have a hundred year old house and this was the easiest repair yet. This fit perfectly, and was the perfect replacement size. It was so easy to do, it’s a high quality knob, and it works!!

    • Ok for the price. Much more flimsy than expected.
Color: Bronze Size: 2-1/4 in.
Not sure how they can advertise as solid brass; it’s definitely not. It’s two hollow pieces attached together; perhaps each piece is all brass. Works ok; shaft was definitely shorter than the one it replaced, and I’m not sure how long a single set screw will keep it securely fastened. Only reason it’s not rated lower is that it’s decently cheap. I’d gladly pay more for a higher quality item though. ... show more

    • Works GREAT
Color: Bronze Size: 2-1/4 in.
I bought an old house with old interior doors and one door had no knobs. All the works were there but just no knobs. So I had to always leave the door open because if it closed I couldn't open it. This was a closet door so I could 'nt keep the curious cat out of it. I finally searched Amazon for an answer. I am beyond thrilled with these knobs- they have an old fashioned look and were so easy to install. Just remember to loosen or remove the tiny screw so you can adjust the knob onto the steel shaft- the re-tighten the screw. Thank you Amazon - I love these knobs and the cat is now kept out of the closet. ... show more
