Front tilt rod, hidden tilt rod or gear system?
Identify your shutter connection and compare the louver preparation before selecting a front, hidden or gear-system installation kit.
Your shutter's connection style determines how its louvers move together. Before choosing a replacement, look at both sides of the panel and compare the original louver ends. Matching the width and color is only part of the fit.
Start with a visual check
Open the panel enough to inspect the rear without forcing its hinges. Find the part that links the louvers. A visible rod across their front usually identifies a front tilt arrangement. A rod behind the panel identifies a hidden rod arrangement. A clear front surface alone does not tell you which system is inside.
| System | What to look for | What must match |
|---|---|---|
| Front tilt rod | A visible rod on the front, joined to the louvers | Louver preparation, U-staple connection and matching front kit |
| Hidden tilt rod | A connecting rod behind the panel | Rear connection, fixed notch, pilot hole and matching hidden kit |
| Gear system | An end connection that engages the shutter's gear mechanism | Gear-slot shape, position, opposite end and compatible gear kit |
Front tilt rod connections
The front rod links the louvers through their front attachments. Compare the location and orientation of the original U-staple connection with the offered preparation. A kit for this connection does not establish that the louver body, end pins or existing rod will fit; check those details separately.
The example below helps you recognize the arrangement. Compare it with your own assembly before reconnecting any part.
Hidden tilt rod connections
A hidden rod runs behind the louvers. In the offered example, the replacement louver preparation includes a fixed notch and pilot hole for the matching connection. Compare these features with the original, including which end and side carry the connection.
Similar-looking rear rods can have different profiles and attachment layouts. If you are replacing a rod as well as a louver, compare its length, connection spacing, number of connections and first-connection position with the original. Choose from the specifications actually offered on the relevant listing.
The hidden tilt rod video is silent with English captions. It shows one connection example and should be compared with the assembly already in your shutter.
Gear systems need a separate check
Some shutters use a gear mechanism rather than an external connecting rod. Check the original louver end and how it engages that mechanism. Compare the offered gear slot and opposite round-hole preparation carefully. Do not select a hidden-rod kit simply because there is no rod visible from the front.
No gear fitting tutorial is included in these videos. Follow the original system's procedure or have its compatibility checked before attempting that repair.
Complete the measurement checklist
After identifying the mechanism, confirm material, body length excluding pins, face width, thickness, profile, finish, preparation, kit and quantity. Read the measuring guide for the offered dimensions. Aging and lighting can affect color, so an exact match to your existing finish cannot be guaranteed.
We supply replacement components. Tilt rods and complete panels are not included with a replacement louver unless the selected listing explicitly states otherwise. On-site installation is not provided.
