Why plastic? Because:
1) Metal would put unnecessary added weight on the garage opener mechanism
2) Metal (in some environments) is susceptible to rust
3) Metal is more reflective, and a criminal with a flashlight may detect it’s presence
Plastic is lighter in weight, made with durable 100% ABS black plastic that doesn’t reflect flashlights well, is rust proof, and can be more easily assembled using plastic snap on fasteners (no tools needed). Don’t let the design fool you, there were over a dozen prototypes created of the Garage Shield to bring you the best result possible.
