The track
Everything interesting happens at the edges
A gap at the side undoes the whole screen. An insect mesh with an open edge is not an insect screen, and a solar panel that bows away from its track stops doing its job at exactly the moment you want it. The retention system along the sides is what holds the material in place through wind, and it is the difference between a screen that gets used and one that gets abandoned.
MagnaTrack® uses a magnetically retained side track. The practical consequence is that the material can be released and re-seated rather than tearing out of a fixed channel.
- The mounting surface has to carry the track, not just the housing.
- Side track routing decides whether an opening is workable at all.
- Post width and column material change what can be fixed where.
