Follow these simple steps to tighten a closet door knob, whether they are equipped with lock a lock or not.
Step 1—Use your screwdriver or hex wrench to loosen the set screw on located on the sleeve of one side of the knob.
Step 2—Unscrew the knob on that side of the door (Knob A) until the spindle is exposed. Tighten the set screw on the other side of the knob (Knob B) until it is very tight.
Step 3—Turn Knob B until the flat part of the spindle is facing up. Push Knob B into the door and hold it in place. Put Knob A back on the spindle while keeping the Knob B firmly in place.
Step 4—Knob A should be against the door, but not too tight. Turn it to get the set screw in alignment. Then put the set screw back in place. Screw tightly.
Step 5—Check the knobs to make sure they move freely but tightly against the door. Repeat the process if the knobs are not tight enough.
Regularly check all doorknobs in your home to ensure that they are working properly.
Depending on the age of the doorknobs on your closet doors, you might have to take the whole doorknob apart to find the screws that need tightening. Modern door knobs have the set screw in a visible location so that you can easily find them, though some older model doors have a hidden chassis mechanism that will require you to take the entire knob apart.
Replacing a closet doorknob is a simple process as well. You can find a number of doorknob kits in your local hardware store that will have everything you need to attach a new closet doorknob. Adding a more modern knob to an older home will give the room an updated look. Choose door knobs that fit in with the room décor and you will add another decorative element to your room.
