Are all door knobs the same?

Posted by on March 6th, 2020

That's my question, not yours! A lady who came by our house one day began stripping all the switches off our door knobs. I've never seen anything like it, and if it's common, then all other doors should be pulled down to the same level of disrepair. Keep this issue in mind. It could be a traditional mechanical problem, a common door replacement, or more reason to shop at Manfrotto and Pescador. Thank you for any feedback you might have.

A: I have two versions of door knobs that I've been told are slightly different. The door knobs pictured below are the same, except

Yes and no. Different applications and tools tend to use different types of Knobs. For example, SAABs can only use the analog unit type and roller remote type lights can only use the LED type. But there are different reasons why they will use them.

Knobs become available for purchase as they get closer to release and sales are restricted to SAABs. If you do happen to have a stock of each type on hand, it's possible to get two pairs of those which is equivalent to one SAAB knob. However, it's a bit of a hassle to go and swap them, especially if you have more than one of the same size for yourself and a SAAB.

How come some are backwards and some are forwards? Should they be made of different materials, should they look different, should they move differently? Should they sound different? Should they have different functions? Should they even exist? The answer is all of the above. If you get too far ahead of yourself, you might get frustrated and give up. But, there are good reasons for some door knobs to be very different from each other, for the best protection, but also for the ease of use and quality of the knob. Here are some of the differences between the various door knobs, and some of the reasons behind them.

Disparity between the doors

By default, doors have basically four basic In most cases, the door set, which is inside of the door and controls the door latch, will be one of two measurements, either 2 3/8 inches or 2 3/4 inches. Virtually all modern door knobs will work within these parameters.

It depends on the size. Door knobs larger than 1.25" (6 mm) should have 12.3mm or 15mm stem and larger (estimated). Larger (estimated) car door knobs also have more knobs to allow for more knobs in a row (this allows them to sit more flush against the top of the door). Smaller (estimated) car door knobs need to have a smaller stem and need less knobs to access the handle.

What is the biggest sign I need to come in? Examine your car door, locate the highest point at the top of the door and double it. That is the largest height possible from the flat surface.
