This morning I was sorting through parts from a completed restoration. I came across some old door lock cylinders without keys. I went to my stash and found 2 that already had the end clips and levers removed. I decided to cut all the extra material off and see what the difference was? The first picture shows the cylinders already cut with the pieces on the scale. They weigh 2.8oz. I'm sure with the end clips, levers and tumblers it would be in the 3.5oz range for the pair. The second picture shows just the end caps that I will clip to the doors at just 1oz!!
