This last weekend I installed some Halo retrofit LED kits into some can lights that are approximately 45 years old. (Pretty sure they were from Sears because they still had the Sears incandescent original bulbs installed) No way to identify the model easily, even if that would tell you anything.
I used the "torsion springs" as the directions recommended, (because the last valence used torsion springs) the holes lined up.
Problem, the springs will not hold the valence tight enough to the ceiling and it show 1/16" - 1/8" gap between the valence and the ceiling. At first I just thought it was just the popcorn ceiling, but now I noticed that I had the same issue in the great-room with a smooth ceiling.
How do I tighten these up to close the gap ? Halo Model:
