The product arrived as expected. However, it would be useful to review the documentation prior to purchase. For example, the manufacturer recommends one unit every 8 feet of ridge. This mean I may need to order more.The building was built with dimensional 2x (2.0-inch) rafters. Would be great if the product was offered in slightly larger size, but not such a big deal because nominal 2x (1.5-inch) can be sistered to the original framing.
