Buying Guide: Key Purchase Considerations
What window types do these kits support?
Most kits are designed for vertical or horizontal sliding windows. Look for adjustable length ranges (around 16.9″ to 62″ or longer) to fit your window height. Check the rail design and whether the sealing panels embed into existing tracks.
