Question: Not sure I understand yet... can I use these to replace the 1980s shiny brass door knobs without additional hardware or modifications? Thanks!
Document: For the incredibly affordable price these are, the quality is great. They look very nice when installed but I wasn't aware that they wouldn't fit into a standard door hole without their own rosettes. That was my mistake so I had to replace two sets of doorknobs and rosettes but the rest of them fit perfectly into my original 1920s doors.
Wasn't sure if this would be a suitable replacement for a worn out spindle and door knobs.These are nice glass knobs. They feel substantial, are seemingly well made and worked perfectly in the door.I'd surely recommend these to anyone needing this kind of replacement part. A good deal and they look great.
This is exactly what pictured&#8230;glass door knob and spindle set. I used it to replace the same/similar one that was in an existing bathroom.
As some other commenters noted, for the price this is a quality item. I got them thinking I would use them on seldom used doors &#34;just for looks&#34; -- I did not expect them to be very strong -- but they are actually just as good quality as the $100 ones they carry at upscale hardware stores.
The basement door to my 1927 craftsman-style rowhouse has been missing a glass knob for so long...anything would do. For 10 bucks it's totally worth it. They are a little smaller in width than my original knobs, but they look great -- I doubt anyone but a professional would ever know. I'm quite happy with the quality and the look and they are solid and well made. They were easy to assemble and fit perfectly.
We were in a antique store with our granddaughter looking at all the nice and pretty older things when we came upon these glass door knobs. When we got back home our granddaughter told us she like the doors knobs and would like to have a set on her bedroom. The antique ones were a little pricey so I looked on Amazon and found a nice set. Ordered them and when she got them her father put them on her door. Looked very nice and she was very happy.
I have not yet installed it but it seems to be of good quality. A good replacement for an old antique knob that fell off and disappeared.
We have a coat rack at our back door and we used old glass door knobs as hooks. One of the knobs broke and we couldn't find a replacement. These glass knobs will work perfectly, plus we'll an extra one.
these doorknobs work great and look great. I needed these knobs for my old home with old doors. it works great.
These knobs are beautiful and work perfectly in my 100 year old house. The only issue is that there was a screw missing from 2 of the three packages I bought. Amazon gave me a partial refund, so I can go out and get replacement screws, but I'd rather they had come in the package like they're supposed to so I don't have to make a trip to the store. Sort of takes the convenience out of ordering online. Great knobs though, if you have all your screws!!! !
