Shoutout to the guy in my shop who still checks hoistway doors with just a flashlight

I keep seeing guys skip the door roller force gauge and just shine a light down the gap. Last month, a call back for a sticking door on a 15 story building in downtown came from that exact shortcut. The specs say 30 pounds of force max for a reason, it's not just a nice idea. I had to recalibrate three floors because the rollers were binding from misalignment you couldn't see. How many of you still use the gauge every single time, or do you think a visual is good enough?

Grab the gauge. That light trick misses the actual force.

Man, you are so right about that. Seen too many people skip the gauge and just eyeball it with a light. That never tells you the real story, just where the gap is. Gotta measure the actual squeeze or you're just guessing. Solid advice right there.
