24 Gauge Galvalume Hidden Mount Strap for Plain Square or Round Downspouts

Available Several colors. 24 Gauge Galvalume Steel. Downspout wall attachment.

Downspout straps come pre formed to fit our standard plain square or round downspouts. This hanger is designed to get installed to the wall before you install your downspout and then the legs can be screwed or riveted into the side of the downspout. Can be used with our standard downspout strap. ***Select the 1 1/2" depth option if using in conjunction with our standard downspout strap.***

At least two downspout straps are required for every 10 feet of downspout. Three are usually sufficient for a straight 20' foot run.
For a 10 foot run, place a strap approximately 1' from the bottom and another 1' from the top. For a 20' foot run, use the same adding a strap right at the seam between the 2 downspouts, which also hides the seam giving it the appearance of a continuous length when used with our standard downspout strap.
