The Hook brackets are highly recommended for ease of installation. In addition to the tab under the collector as used in the L bracket, a second tab acts as a hook and allows the installers to safely rest the collector's weight on to the strut channel before inserting the channel bolts. This is highly beneficial during installations in difficult roof-top positions, preventing the need to manually support the weight of the collector while fastening the bolt.
Safe and very flexible, it allows for sloped or flat roof, rack or wall mounting to best meet your needs. |
