The Copper Half Round Reverse Bead Hanger is made exclusively for our 6" half round copper reverse bead gutter. The hanger clips into the front bead (similar to a traditional k style hanger) and a zip screw or nut and bolt should be used to hold the hanger to the back of the half round gutter.
The reverse bead hanger needs to be used with another gutter hanger accessory as the hanger alone is not enough to support the rounded shape of the gutter on a flat fascia board. The hanger is slotted to accept our threaded rod (sold separately), which gets attached to the roof deck. And we also carry copper gutter wedges which will also support the gutter from underneath.
Depending on the application and depending on the snow load, recommended spacing is 18"- 32".
