Flylock 5Pcs 2.5 Turn Replacement Spring for The Door Handle,Turning Lever Door Handles Lock Internal Repair Replacement

Used this on a 2002 Emtek passage door handle that had a broken torsion spring. This worked perfectly no adjustments needed to be done just had to lubricate the spring.

Replaced a broken spring in our circa-2007 lever-style EMTEK door handle. 2.5 turn is just right, overall size is fine, maybe slightly thicker than the original but that's accounted for by removing one of the thin brass spacers.

At the time I write this, an "official" replacement spring is around fifteen bucks, and these Flylock replacement springs are only two. Of course, it's tempting to see if you can both save some money and also have a set of spares for future replacement. Since it's not that much, I went ahead and ordered both to compare the two. The main thing I noticed is that the turns on the Flylock springs are different from the official replacement. If you orient the springs so that the inner tab points straight up with the spring winding clockwise, then the original spring ends up at around the 8:00 position, while these Flylock springs stop at the 6:00 position. Now look at the OEM spring in place: the two tabs are in line, so there's a bit of tension at rest. The Flylock spring has no tension at rest, so the handle will immediately sag. Notice also that outer tab is too long. One solution might be to place the short tab in the opposite slot, winding the spring a half turn to the outer rest. However, this places too much tension on the spring, making it quite difficult to install, and I found that this caused the spring to wind underneath itself so it wouldn't lie flat. I _was_ able to get this to work by bending the Flylock spring at the 8:00 position and cutting the spring outer tab to the proper length. In the end, this worked just fine, but you'll need to play with a vise and strong plyers to reshape. While messing with this, I also rebuilt the exact same style Emtek latch from one of our inner doors, and found that the two springs were quite different. One was something like 2⅓ turns, while the other was 2¾ turns, so be careful. Perhaps this doesn't really matter, and you can just locate the short inner tab to get things to line up.

Not exactly the same for my Emtek hardware but made it work.
