This gutter hanger is made to fit our reverse bead half round gutter. The stainless steel hanger clips into the front bead (similar to a traditional k style hanger). A zip screw or nut and bolt should be used to hold the hanger to the back of the half round gutter. The hanger is slotted to accept our threaded rod (sold separately), which gets attached to the roof deck.
It's recommended that a threaded rod or gutter wedge is used with these gutter hangers for strength, half round gutters are round and must have something to support the front of gutter, or brace the back.
Stainless Steel is stronger and compatible with Copper and Aluminum.
