Shoreline RV2050 Round Floor Roller and Hatch Kit

The round roller bearing works well. The quick open hatch works well. The only problem is that it appears that the two are not designed for each other, as the size of the roller bearing does not fit well with the hatch. I made it work, and it does work fine, which is the main thing, but the screw-holes for the bearing plate do not line up well with the plastic hatch surround, so cosmetically, things are way off and some mounting holes are not usable. Still, the bearing allows the power cord to retract and roll-up easily into the RV compartment, which is the main thing!
