Metal Door Closer

Broken Arm Repair Procedure

  1. First, climb up and examine the closer carefully to ascertain the exact position of the crack. If it is the arm, then the door would not close the way it should. The arm shaft is square, meaning if the part connecting the arm to the shaft isn’t square due to rust from exposure to environmental elements and friction between the arm connector and the shaft, then you would notice a crack on a section of the connector.
  2. This type of crack would require you first to hammer the shaft connector on the arm to flatten it up.
  3. Get your welding machine and weld some metal on the crack to seal it.
  4. Then you would need to carefully add some additional welding metal bead around the hole to make it fit the latch connector tightly. The metal bead should be molded to fit around the square hole snugly.
  5. File the edges of the welding on the arm with a metal file to remove any uneven surfaces.
  6. Attach the arm to the latch and close the latch using your wrench, checking whether the arm fits securely on the latch.

Cracked Internal Springs

The internal springs controlling the speed of the closer accumulate rust over a long period, they would get weak and eventually break.

  1. To fix this anomaly, you would first open up the outer cover by snapping off the cover fasteners to reveal the spring tube.
  2. This tube has a tension adjustment knob, which can be turned to either increase or decrease the tension, thus affecting the speed at which the door closes.
  3. This knob can be turned completely to reveal the springs inside.
  4. Remove the knob and replace the springs with an exact match for that closer.
  5. Place the spring tube knob carefully, ensuring the springs latch on correctly to the knob.
  6. Close the knob to the correct tension and restore the outer cover before testing the door.

If the spindle is broken such that the arm cannot leverage the speed at which the door closes, then you would first have to determine the exact spindle model before purchasing it at your local door repair Burnaby hardware shop.

  2. Open the outer cover to reveal the internal components.
  3. Remove the spindle using a wrench.
  4. Carefully insert the new spindle and reattach it firmly using a wrench.
  5. Reattach the closure arm tightly.
  6. Test the door.

These procedures might seem a lot, but with the correct tools, repairing your door closure should be a breeze and cost-effective in the long run if you do it yourself.
