Made from 16 ga steel and powder coated gloss black to match the cage.  The sides are folded over twice creating a 1/8" angle around the outside making it very it very durable.  It mounts with EMP "Quick Connect Clamps" using (6) bolts so you can easily remove the top.  The clamps will remain on the cage so you can easily mount it again.  Will work with most windshields including the EMP Full Windshield.
