Installation demonstration of the LCN 4040Xp Closer. Also shows adjustments. This example is installed on the push side of a right-handed hollow metal door.
At 6:50, the installer is using screws for a metal door and not wood screws. This closer will eventually be pulled out of the door. This door needs through bolts now because of this error.
7:07 Unfortunately, the installer Jeff makes a major mistake here. He preloads the unit first, which is correct, but you then should put the arm on parallel to the door so when you release the wrench, the arm will be pushing against the door, almost in it's final position, but it will be under tension. This is called "preloading". But he moves the arm around, unable to find the hole, then finally swings it right out to the same angle as the wrench and puts it on there! Now when he lets go the wrench and the whole arm swings back to its original position, undoing the preloaded tension he had just created. This is covered quite clearly in the 4040XP instructions. The purpose of preloading is so the arm will have enough tension to pull the door shut, even over the last 2 or 3 inches of travel.
I went back and watched that. You are correct. The arm should have been installed parallel with the door not at the 30 degree angle. Now there is no preload.
We try to install it today but had no succes , it does not mean we cant , it means now ill get it done thank you for the video
These LCN closers are super annoying to deal with.

Why did he not use the template for drilling the holes?
That body is way to far out to the middle of the door it should be closer to the edge otherwise the door wont open all the way
What tools do you need for this?
