Our read on this product
This security door strike is designed to solve a specific problem: the vulnerability of standard door jambs to forced entry. It replaces both the latch and deadbolt strike plates with a single, heavy-duty unit, offering a more robust defense against kicking or prying. The combination design simplifies installation and repair, making it a practical upgrade for homeowners looking to enhance their peace of mind.
While it's an easy installation for most, the key is ensuring your door frame's hole spacing matches the 5-1/2 inch center-to-center requirement. If it does, you're looking at a straightforward way to significantly bolster your door's resistance to break-ins. It’s the kind of upgrade that quietly makes a difference, especially if you've ever worried about the security of your main entryways.
What makes it stand out
- Combines latch and deadbolt strikes into one unit, unlike separate standard plates.
- Offers a repair solution for damaged wood jambs, not just a replacement strike.
- Available in multiple finishes to better match your existing hardware.
When this isn't the right fit
- Your door frame has a different hole spacing than the 5-1/2 inch center-to-center requirement.
- You're looking for a security solution for a commercial property.
Real-world notes
- The solid, heavy feel of the metal construction.
- The peace of mind that comes with a reinforced door jamb.
- The included screws are long enough to bite well into the door frame.
A confident pick for homeowners prioritizing a straightforward security upgrade.
