Frequently Asked Questions

Q: What types of sliding doors and windows is this zinc alloy hook lock compatible with?

A: This sliding door lock is designed to fit a wide variety of standard sliding door and window frames. The embedded 90-degree hook latch works with most residential and commercial sliding door tracks. We recommend measuring your frame recess before installation to confirm compatibility.

Q: Does this sliding window latch come with installation hardware?

A: The package includes 1 × Sliding Door Lock. Installation hardware such as screws may vary by variant. The lock's embedded design is intended for recessed installation into the door or window frame for a flush, invisible finish.

Q: What is the difference between the single-sided and double-sided lock options?

A: The single-sided lock comes with a key, allowing you to lock and unlock from one side with added security — great for entry doors. The double-sided lock operates without a key using the slide mechanism on both sides, making it ideal for interior spaces or areas where key-free convenience is preferred.

Q: Will the electroplated finish resist moisture and rust over time?

A: Yes. The electroplated layer on this zinc alloy sliding door lock is specifically designed to guard against corrosion and rust, helping the lock maintain its appearance and functionality even in humid environments such as bathrooms or kitchens.
