Twin-Band Downspout Wall Standoff
This is a wall-mounted standoff block for a gutter downspout. It measures 130 x 60 x 11 mm and screws on with two #10 or M5 screws (5.5 mm countersunk holes). Two 14 x 3.5 mm tunnels run through it for zip ties or 1/2 in (12.7 mm) worm-drive hose-clamp bands. The band wraps around the downspout, so one part fits 2x3 in (about 51 x 76 mm nominal), 3x4 in or any other profile, and it replaces the brittle vinyl straps that snap every winter.
