The force of thrown snow from a plow blade can be substantial and may cause damage to the mailbox and/or post. Some residents have constructed barriers between their rural mailbox and the force of thrown snow. Barriers can be easily constructed using 4 x 4 posts and 2 x 4's. Below are photos of snow barriers installed by creative Holland home owner's.
In this example the homeowner used a single 4x4 post with 4, 2x4's horizontally at the height of the mailbox.
