Lewmar Ocean Hatch Small Handle Kit

I did not need an adhesive once I drilled a whole through acrylic glass as there was screw to mechanically secure inner and outer pieces. The two inner cone shape pieces had different surfaces mating with glass; one had small nub just outside center and the other had two slightly elevated plastic slivers either side of center hole of cone shape piece. I drilled small indent for first version of cone and that seated cone to bottom of glass at center of hole.

The new parts ment drilling whole through acrylic glass and attaching screw fastner in hatch handle.
