Z-Articulating Cap Sill

Never Adjust a Sill Again.

In addition to the benefits of our adjustable sill solution, the Z-Articulating Cap Sill (Z-AC) automatically adjusts, saving time, eliminating maintenance needs and service calls, and delivering constant protection against leaks, drafts and insects, even when conditions aren’t perfect or change over time.

Cut costs, not corners: With Z-AC, you can work smarter – not harder. The Z-Articulating Cap Sill eliminates extra installation steps and common headaches, works in imperfect conditions and overall works with the limited labor resources you have, while doing the work of the labor you don’t.
