Using a patented design of all-synthetic components, the Z-Series Sill eliminates the worries of wood. Built to last, Z-Series Sills protect your entry from unsightly damage, rusted screws, discoloration, deformity, gaps and dents.
No more stuck doors or drafts because the Z-Series Sill substrate material is a waterproof composite that won’t warp or rot, ever. The substrate is not affected by moisture and rot like wood.
High Dam, Integrated Seal
Innovative cap design overlaps at the dam to provide a barrier against air and moisture, even in extreme weather conditions.
Sealed Adjustment Screws
Sealing plugs hide unsightly screws and keep water and dirt away from the adjustment mechanism, maintaining adjustability of the sill cap over time.
