## Product: 24-Inch Gate Extension
**Brand:** Carlson

## Pros
- Easy to install, typically in less than 10 minutes, with many reviewers noting a straightforward setup.
- Can reuse the existing black plastic bar, saving time and effort during installation.
- Made by Kohler, a brand perceived as higher quality and more durable than generic options.
- Constructed from robust plastic, which feels more durable compared to stretchy rubber versions.
- Successfully resolved issues like leaks and ghost flushing for many users, restoring proper function.
- Fits Kohler low tank toilets, particularly models like 3384, 3386, and K3467, with proper compatibility checks.
- Some reviewers found that aftermarket parts, like this one, can be more reliable than OEM replacements.
- Provides a proper seal and stops continuous water movement in many cases.
- The part's design allows for easy reinstallation and adjustment if needed.
- Noted to be more effective than previous non-OEM flappers, with longer-lasting performance.

## Cons
- The picture-based installation instructions can be unclear, leading to some confusion during setup.
- May not fit all Kohler models perfectly, so double-check compatibility before buying.
- Some reviews mentioned the hinge isn't wide enough, leading to imperfect seals or ghost flushing.
- Minor difficulty in installation due to differences from previous rubber flappers, especially sliding the plastic bar.
- A few users experienced persistent leaks or water dances in the bowl if not installed properly or if the seal isn't perfect.
- Compatibility issues could cause leaks or improper flushing if not carefully verified.
- Overall, a few users wished for more detailed, clearer installation guidance.
- May require wiping down the seat area for a better seal and to prevent ghost flushing.

## Bottom Line

This Kohler Extra Tall Gate Extension 24Inch is generally well-regarded for its durability and ease of installation, especially if you’re comfortable with basic DIY plumbing. It’s a solid choice for replacing worn-out flappers, especially since many reviewers reported successful fixes for leaks and ghost flushing. However, take care to verify compatibility and read installation instructions carefully, as those picture-based guides can be confusing. If you’re looking for a product that’s likely to last and offers reliable performance, this model is worth considering—but if you want a more foolproof fit, exploring alternative brands like Korky might be wise.
