Salsbury Industries 4 Wide Spreader for Roadside Mailboxes

Eliminate wind-blown mailbox closures with the widest Salsbury Industries spreader option — a heavy-gauge steel 4-inch wide plate that locks your roadside mailbox arm at the ideal delivery angle. High-speed traffic no longer knocks mail loose onto your driveway.

Salsbury Industries engineered this maximum-width spreader for properties that need maximum stability. The corrosion-resistant finish handles years of road salt, UV exposure, and weathering without deteriorating. Prime Mailships carries it in four colors — Black, Bronze, Silver, and White — to coordinate with your mailbox hardware.

Fits standard roadside mailbox and mail chest arms. Measure your arm width before ordering the 4-inch version at Prime Mailships for guaranteed compatibility.
