Coverage & How Much You Need:

Hangers are typically spaced about every 24 in. along the gutter run, so a 100-count box of 5 in. hangers covers roughly 200 ft. of gutter. Order one hanger per 24 in. of run, plus extras at ends and splices.

Fit and Compatibility:

Use the 5 in. hanger with 5 in. K-style gutters and the 6 in. hanger with 6 in. K-style gutters. Fasteners and ferrules are sold separately.

Expert Verdict Reviewed by the SuperArbor Pro Desk

Backless hidden hangers are the standard choice for strength and appearance on K-style aluminum or steel gutters; choose the size to match the gutter, not the fascia. Snap a chalk line for slope, roughly 1/4 in. per 10 ft., and set hangers to that line before fastening. Galvanized hangers pair best with galvanized or painted steel gutters; on bare aluminum runs, aluminum hangers avoid dissimilar-metal contact.

Work from a secured ladder and wear gloves and eye protection when fastening metal hangers.
