Doors and Windows - Need an extended striker plate for wide door frame

I used a prehung door with the width of the frame set for drywall in a plastered wall. Should have used the correct width but thought that I could "frame the inside with 3/4" deed by 5/8" wide molding and then cover this with the outside door molding. This works fine -- except -- now the striker plate tongue is too short, I need an extended one (1/2" to 3/4" would seem to work ok.

Any ideas on where to purchase something like this or does it exist? Any other thoughts on how to keep the door latch from striking the frame before it gets to the short standard striker plate tongue.

I know -- the correct way would be to install the correct width pre-hung door in the first place. The local Home Depot did not have one and I did not think of this striker problem until after the door was in.....

Thanks,

So you added a small extension jamb onto the strike plate side of the door, and now the strike plate won't work? It sounds to me like you needed to leave more of a reveal around the jamb when you put the extension jamb on. I vaguely remember doing the same thing once a long time ago! :wall:

I have not put the extension on yet, I can offset it and the reveal should work and there is room for it. This should clear the door latch. I will give it a try to see what I can do.

Thanks for the suggestion.

What's done is done, but next time, remove the brickmould and install the jamb extension onto the exterior side of the frame. They actually make jamb extension kits in 5 1/4" (most common) and 6 9/16", they come with the 2 sides, top, and sill extension for about $20-30 bucks-usually cheaper to buy a stock door and do this yourself as opposed to custom ordering a unit per jamb width specs.

i personally hate the interior side build out on jambs, gets into too many problems with the hinges, striker, etc...your on the right track, but they do sell striker plates for such things at homecenters, so come premade to a certain extension, other are adjustible.

Oh, maybe I got the wrong impression! I thought this was an interior door, not an exterior door!

IHI is right about the extension jamb going on the outside of an exterior door (behind the brickmould). And if it is an interior door, try to avoid putting the extension jamb on the hinge side (strike plate side) if at all possible... for the reasons IHI mentions. The hinge side always needs to be mounted flush with the interior wall surface.

The way it sounded at first, I imagined it was an interior door that had already been shimmed and nailed in place.

The door is an interior door and it was nailed in, I just had not put the extension on yet. The next door I do will be extended on the "non-hinge" side as I can clearly see the wisdom in this now.... live and learn.

Thanks again to everyone for the posts!! Really appreciate it :)

Dave, It exists....
I noticed a few days ago the local lumber yard I do business with Sells an extended latch plate for jams with extension jams...I'll write down the name of the company on the package and post it tomorrow. It looked like it would cover up approx 5/8 to 3/4..

Dave,
The latch company is called mag... I noticed it is sold in the doityourself.com store...

Stephen,
