How to identify your interior shutter type
Identify the panel layout, louver size, tilt control, frame and mounting style. A clear set of photos is more useful than a retailer name alone.
Step 1
Record the visible features
Note full-height, café, tier-on-tier or specialty panels; louver size; frame shape; hinges; and whether the tilt rod is visible.
Step 2
Observe the movement
Open the panel and rotate the control. See whether all louvers move together, whether tiers move separately and whether any louver binds.
Step 3
Why identification matters
The physical layout narrows measurement and compatibility questions, but it does not by itself establish support for a specific product.

Decision framework
- Identify the physical motion.
- Measure the opening, mechanism and clearance.
- Check power, manual fallback and control ecosystem.
- Verify the exact product or request compatibility review.
Common questions
Is ‘plantation’ enough information?
No. It describes a common louver style, not the complete mechanism or installation.
What if I cannot see the mechanism?
Record that as unknown and provide photos of the louver edge and panel face.

Visible tilt rod versus hidden tilt shutters
A visible tilt rod is an external bar connected to the louvers; a hidden tilt mechanism puts the linkage behind the louver edge. The distinction can change retrofit options and how a shutter is operated.
