Extended Strike Plate For Mortise Style Doors

thingiverse

Sometimes these door strike plates wear out over time, or the actual mechanism in the door (the bolt of the knob or the bolt of the lock) fails due to long term use, lack of lubrication, rust, etc. Anyway, Once a door starts sticking, you can do the following: A. Replace the Mortise lock system, not that expensive, maybe 20-30 bucks and it works great. B. Shim the original strike plate so that it reaches further out C. Shim the door hinges so the door reaches further out, and by extension the bolt will reach the strike plate. D. Keep using the old mortise system and print this piece, which will extend the reach of the bolt. If the bolt is only coming out halfway, well now it will reach. Feel free to edit the Z height of this to your needs. The hole in the middle is large enough to accommodate most knob and lock bolts (both bolts in the one hole). The screws are for flat head #8 screws with 4 mm thread. My house is old so I used #8 x1-1/2inch wood screws with a flat head. 3mm head depth, 8mm head diameter, 4mm thread width for the holes; That way I can get in real deep in that delicious, rotting wood.
