I have installed small recessed lights in a house that i have renovated. These recessed lights have trim that simply staps into place. The bulb is also supported by this trim (slides into tension fork kind of thing). For one reason or another the can for some of these fixtures is too high in the ceiling and will not allow the trim ring to snap into place. In addition a few of the fixtures have slight movement in them (20" o.c. joist in a house built in 1890) which does not allow me to apply enough force to get the ring to go in the fixture for enough for the clips to snap past the ring on the top of the trim. Can i glue these rings into place? How would i then clamp or support the trim long enough for the glue or caulk etc. to set up? Please help me with this so that my project can look complete.
