Maurice Franklin Louver 6 in. W x 6 in. L Bright Silver Aluminum Mini Louver

Used these to vent the V Crimp Metal Skirting on my mobile home. They worked great and are narrow enough to be installed between the crimps of the tin so I didn't have to cut across them. Don't expect them to sit flat. Use some self tapping roofing screws around the edges.

These were not what I expected we had to drill holes in them to get them to stay on.
