Frequently Asked Questions
- What is a multipoint lock for sliding doors?
A multipoint lock engages multiple points along the door edge, increasing security against forced entry compared with single-point locks.
- What does “11-3/4 inch face plate” mean?
It refers to the length of the face plate that sits against the door frame, a common size for sliding patio door mortise locks.
- Is anti-slam feature important?
Yes. Anti-slam buttons prevent damage to lock hooks when the door closes hard, extending the lock’s life.
- Do these locks fit all sliding doors?
Fit depends on hole spacing, face plate size, and handle/lever compatibility. Always verify your door’s measurements and hardware before purchase.
- Should I replace the entire door or just the lock?
If only the locking mechanism is worn or damaged and your door frame is sound, replacing the lock is often sufficient and less invasive.
- Are screws included with these locks?
Some listings note that attaching screws are sold separately. Check product details and buy the appropriate fasteners for your frame.
