WW: Centsational Installation

Step 4:  Invert the cylinder cam as shown.

Or use your creativity to avoid looking at the instructions.

This photo was sent in by Jon Dudley of Ingersoll Rand Security Technologies.

    I wonder if his invoice included two pennies for ‘shop supplies’?

    Makes cents

    i thought pennies were for fuse boxes

    Don’t laugh, I’ve had to do this! Not because I couldn’t read directions but because we were interfacing our card reader system with hardware provided by others. Our customer needed the door locked but the cylinder was nowhere to be found. I can’t remember exactly what I used but now that I know pennies work…

      I live in fear of posting a photo of what not to do and having an installer see their own photo on my site! 🙂

      It happened to me within the first few months after I started this site. The craziest part was that the photo was taken in Israel and the installer (also in Israel) saw the photo. What are the chances???

  5. J.J. Monteiro says:

    Correct me if I’m wrong but would the key even work to unlock the door in this situation? It seems like they installed the cylinder, it didn’t work to unlock the door and then blamed the hardware.

    My situation involved an rim EL which was another mistake, they should have just provided electrified trim, there was no reason for an EL device.

    That was an interesting story, that closer you referenced above actually looks pretty good, wouldn’t want to have to change it out, looks like it’s in there tight!

    • Lori says:

      I couldn’t figure out how it would work and the person who sent the photo in said that it would bind when you tried to unlock it. I’m sure someone called the IR office because it wasn’t working.

      How do you decide whether an EL or an E should be used?

  6. J.J. Monteiro says:

    I usually wouldn’t recommend an EL device unless the door required it, e.g. a door that requires positive latching as well as an automatic operator. In our situation the door leads into a waiting area, it doesn’t take long for the clunking of the EL device to drive people crazy, the door ends up being scheduled open during the day. An E device would be better as it is silent in comparison.

  7. Jon Dudley says:

    The door would not unlock, so I took it apart to investigate and found the four cents worth of engineering. Here’s your time saving trick – if your key will only rotate 180 degrees, then you must disassemble and invert the cam 180 degrees. Another symptom is if you can jiggle the lever and it unlocks or by force it unlocks.

  8. Ron says:

    one of the things that an inverted cam can be useful for is to make for example, a von duprin 22 outside trim be a storeroom function vs normally a classroom function.. so there are reasons…

    • Lori says:

      Yes, there are reasons to invert the cylinder cam, but this installer chose to use pennies instead of following the instructions! 😉
