This is a more specific & up-to-date version of this question:
LED Recessed lighting trim stuck
The goal is prevention, so this is not a duplicate.
Some new-construction cans (especially it seems 6" cans) typically have "V" shaped springs that hold the light fixture in place. These springs engage with slots in the housing.
However, many 4" cans (e.g. HALO) don't have the internal bracket for such a scheme and expect the trim to be held in place by 3 spring tabs spaced equally around the perimeter of the trim. These 3 tabs are frequently seen on LED retrofit trims at retailers like Home Depot.
I have noticed that these tabs/legs are sharp and tend to cut grooves into the metal of the can and can become very difficult to remove. This is a significant problem because it becomes very difficult to replace the retrofit module if desired or necessary.
This might (or might not) be the root problem of the original poster linked above (there isn't enough information to tell).
However, my question is this:
Before installing 40 retrofits like this, I need to make sure I can remove them in the future if desired. Does anyone have experience with these kinds of mounting springs and have any suggestions on how to make them easier to remove?
Thanks!
