Harbor Mill™ Shake and Shingle Siding

ENGINEERED FOR EASY INSTALLATION

Designed with the installer in mind, Harbor Mill polypropylene siding incorporates built-in features that aid in a more efficient, hassle-free installation. The rigid, lightweight, easy-to-handle panels include:

Drop Guard (A) – Secures the panel in position while the installer fastens it to the wall. This hands-free advantage results in a straighter set-up, and less effort for the installer.
Continuous Lock (B) – Anchors each panel together, providing stability and durability.
Alignment Guide (C) – Prevents the panel from unlocking from the overlapping panel while leaving room for expansion and contraction.
Stagger Pattern Marks (D) – Indicate the order in which the panels are cut to maintain a proper stagger pattern.
Matching Corners (E) – Ensure a seamless look with coordinating shake or shingle grain patterns.
Seam Lock (reverse side) – Makes joint overlaps effectively invisible, even to the trained eye. The result is a smooth, seamless appearance with great curb appeal.

What does this mean for you?

These details make it easier to position and fasten the siding panels—a huge advantage when you’re 20 feet high on a ladder at the jobsite!

To help with a more efficient and trouble-free installation, Harbor Mill packaging includes a QR code that installers can scan to access installation instructions and customer support.

Harbor Mill makes it easy to get the job done quickly, easily, and safely, and move on to the next one.
