Modular Home Door Knobs

[th3w01f]

We're trying to replace the indoor knobs in the modular but can't find anything that fits, the latch hole is smaller and the hole for the knob is closer to the edge than standard door knobs.

Does anyone know if mobile home door knobs will fit?

Awesome, thanks for the info. We've been thinking about just replacing the doors but with 10 of them it's kind of a PITA.

Unfortunately my mom threw all the old knobs away so we can't even show them to someone or compare at a store. We just have to get a new one and see if it fits.

The ones on that site look like they might be what we're looking for.

In my past experience yes, but they are all junk. sadly. In one of our houses we just bought new doors. They make very inexpensive hollow core doors, if you were trying to save money. I think I also just made standard door knobs fit the modular doors in the past if I had too. I think most modern door knobs have 2 settings for depth. When you buy the knobs you can set them for shallow or deeper depth to the jamb.

we have had to buy mobile/modular unique parts here before. Like hinges, if yours has the lightweight ones. (all of this was because we were selling and not wanting to sink money into upgrading, which needed to be done)

Here's some info I found helpful:
Doorknob measurements are fairly standardized, but there are still a number of variables to consider. The standard measurements for doorknobs will depend on the answers to these questions:
· Is the door interior or exterior?
· Is the door blank or pre-drilled?
· Are you replacing an existing doorknob?
To speak the language of doorknob installation, these are the terms to know:
· The bore hole is the doorknob hole.
· The cross bore is the hole that goes from the narrow edge of the door to the doorknob hole.
· The backset is the distance from the edge of the door to the center of the bore hole.
· The latch is the part of the hardware that goes into the cross bore hole. These come in three varieties: drive-in, rounded corner and square corner.
· The shank, or spindle, is the part of the hardware that goes through the door, connecting the knobs on either side.
· A handleset is hardware for an exterior door that includes a keyed deadbolt separate from the knob or lever.
Standard Measurements for Doors and Knobs
When choosing a doorknob — which generally comes in a set including knobs, shank and latch — focus on three key measurements: the thickness of the door, the backset and the size of the bore hole. Most interior doors are 1-3/8″ thick, while exterior doors are typically 1-3/4″ thick. The most standard backset for a door is 2-3/8″, but some doors (particularly exterior) have a 2-3/4″ backset. The standard cross bore has a diameter of 1″. The standard shank size of a doorknob is 1/4″.
The standard diameter of the bore hole is 2-1/8″. If you will be using a hole saw to drill the bore hole, the standard height is a bore hole centered on 36″ from the bottom of the door. In new construction, doors are hung so that the bore hole is centered on 40-5/16″ above the finished floor.
If using a separate deadbolt for an exterior door, the bore hole should be either the standard 2-1/8″ or 1-5/8″ diameter. Handlesets that are one piece require two bore holes — one above the other and typically 5-1/2″ apart center to center.

Kwickset has a mobile home line.

If the latch backset distance will work you might be able to re cut to a larger hole.

It sounds like backset and cross bore are the issues you are asking about. I would verify that your backset is either 2-3/8" or 2-3/4" and the hole is 2-1/8" diameter. If the cross bore is to small it should be easy to drill it out with right sized bit. If your doors fit into those specs you should be able to find standard knobs fairly easy.

[Wulf202]

Not entirety true. Since the backset is measured o.c.

If you dont have 2 1/8th in hole as described but have a minimum of 1 1/16 in of wood over the latch you can still drill a larger hole and salvage them. Your larger hole will just be off center of the old one. Ryobi has a jig available at depot thats not expensive and will work fine.

Tried the Kwikset and it worked fine, the original ones she purchased from Home Depot had a much larger diameter latch. Thanks for the advice and details.
