Who the Ultra-Secua suits
Most smart locks go on the front door, which leaves you still carrying a key for the security screen in front of it. The Ultra-Secua fixes that. Put it on the screen door and the whole entry opens without a key.
If the door behind already has a McGrath smart lock, the two can unlock together, so one code or tag gets you through both. This doesn’t work with some older McGrath units, so we check which one you have. It also suits a screen door on its own, such as a back door you use more than the front. See our security screen door locks page for other options.
What we check before we fit it
- Your current screen lock. The Ultra-Secua is made to replace most screen door locks. We look at yours and tell you what has to change.
- Door thickness. McGrath notes screen door frames vary, so we measure the frame before you order.
- Hinged or sliding. It is made for hinged screen doors. If yours slides, we check with McGrath before we say it will work.
- Triple locking. It works with triple locking screen doors, and we check all three points throw and release properly.
- The door behind. If you want the two doors to unlock together, we check the McGrath lock behind is a model that supports it.
Living with the Ultra-Secua
- Batteries. It runs on 2 CR2 3V lithium batteries, and McGrath says they last 3 to 4 years.
- Low battery. You get a beep at the lock and a warning in the app well before they run out. Keep the backup key handy for the day they do.
- Reach through. It has a guard against someone reaching through the mesh to work the inside handle.
- Weather. The outside is rated IP66, which matters on a screen door out in the weather.
- Passage mode. Leaves the screen unlocked while you’re in and out.
- Codes. Extra digits hide your code, and 5 wrong tries locks the keypad.
- Wear. McGrath has cycle tested it 300,000 times.
