Existing Opening Frame
Existing opening frames are sized for installation into wall openings that are already fully built out — making them the right choice for renovation projects, replacement applications, and retrofits where the wall cannot be modified. Available in adjustable and fixed-depth configurations.
- Designed for installation after wall construction is complete
- Adjustable depth versions available for variable wall conditions
- Snap-in or screw-anchored installation methods
- Available in standard and custom opening sizes
