I bought these to wall mount a garden tool, following an example recently published in Family Handyman magazine. It provides adequate ventilation within a 4 foot wide and 8 foot high ledge. I placed it high up on a 16" wide side panel and drilled a 3" hole with a hole saw. The siding was cedar and it wobbled a bit (probably due to my hole saw technique). A drop of construction adhesive between the vent and side panel did the trick and it sits securely in place and does its job.
