The hood in the image is a 'Sportster' hood. It is made by BAS, who were the OEM manufacturers of the original hoods. The Sportster hood was not offered on cars when new but has been available as a replacement. It is a nice looking design but has a small flaw that the glass does not sit as flat as the OEM style. The effect is that the hood does stick up more when folded down. The reason for the difference is the gap between the glass and the bottom of the hood. On the OEM style the gap is slightly larger (i.e. more material between the glass and the bottom of the hood) which allows the glass to sit evenly when folded.
Not sure about the rubbing of frame against the hood. Perhaps this is part of the design of the Sportster hood. The OEM hoods were prone to getting stuck and frame pinching the materials, causing small holes. This was rectified with easily fitted additional straps. These are available from Rimmers.
