THE IXo
VARIABLE-SWING SILLS
One Sill. Infinite Possibilities.
The iXo Variable-Swing Sill was built to make life easier for door prehangers and installers.
With a quick riser swap, you can convert between inswing and outswing applications,
reducing SKUs, simplifying inventory, and ensuring a consistent, professional fit every time.
A Smarter, More Flexible Sill System
The iXo family combines innovative engineering with practical design. Its composite substrate with integrated nosing provides lasting durability, while the aluminum riser channel allows secure astragal and gasket attachment. Flush-mounted adjustment screws keep everything serviceable without removable caps. Because the best products are the ones built for the real world.
- Convertible Design - Quickly change between inswing and outswing by swapping the riser. One system covers multiple door types.
- Composite Durability - Composite substrate with integrated nosing and aluminum riser channel for a stable, rot-resistant foundation.
