Input:
Question: Can this be installed from the outside? I only have about 30" between roof & ceiling & cannot get to there from inside my crawl space.
Document: Well worth the money plus I should save on energy because I will not have to turn on a light during most days.
Received the product quickly. Was initially hesitant because other reviewers from this seller and other who was selling same product, were stating that the product did not measure up to the name brand sold at Big Box stores. Well, they were wrong. This skylight is every bit as good. It took my husband the same amount of time to install as the other brand. This skylight is a good value and it puts out as much light as the larger big brand does.
Answer: no
