CenterLock
Designed for lasting distinction.

Advanced panel design.
Only CenterLock uses a patened locking system that pulls panels tight to the wall. Extra-thick panels stay flat and overlaps are minimized, producing walls with the smooth, even appearance of solid wood. Added rigidity helps span faults in walls, assuring straight course lines that last.

Unmatched appreance.
The patented locking system also provides consistent "board-to-board" appearance - the look siding is supposed to have.

Outstanding beauty.
Classic 4 1/2" clapboard and dutch lap profiles, along with a richly detailed grained cedar texture adds the look and feel of wood. Deep, realistic shadow lines and low-gloss, look-of-paint finish ass to the appeal. For manimum design flexibility, CenterLock is available in 13 popular colors.

Superior wind resistance.
CenterLock uses an extra tough nail hem to keep panels locked in place, even in winds exceeding 150 mph.

Easy-care maintenance.
CenterLock is made with durable premium vinyl, so it won't warp, rot or peel. And it never needs staining or painting. Just wash occasionally with a garden hose to restore like-new beauty.

CenterLock
Patented design add true look-of-wood beauty.

Realistic look of individual boards.
With ordinary vinyl sidings, you can see a slight variation between the upper and lower "boards" of each panel. But not with CenterLock. Because it uses two locks in each panel, every CenterLock "board" is identical. The result is true look-of-wood beauty.

Overlaps almost disappear.
Competitive vinyl sidings are joined only at the top and bottom, so they can pull apart at mid-panel, causing unsightly gaps at overlaps. CenterLock's advanced locking system keeps panels tight to the wall, producing smooth, flat laps that last, and added rigidity to help span faults in walls, assuring straight course lines that last.

CenterLock gives you all the beauty of a traditional wood siding installation. And with Alside's color coordination, easy-care trim and accessories, you can add striking accents that give your home lasting distinction.
