Shutlok™ – Self Closing Door Hinge with 90° Hold
Finally—Doors That Close Themselves
You ask nicely. You remind them. You put up a sign.
And still—the door stays open. The AC runs. The dog escapes. The bugs get in.
Shutlok™ is the self-closing spring hinge that also holds open when you need it. Push the door past 90 degrees—it stays. Let it go—it closes on its own.
No more chasing doors. No more yelling down the hall. Just install, adjust the tension to your door weight, and walk away.
One of Our Most-Installed Home Upgrades
✓ STOPS THE "WHO LEFT THE DOOR OPEN?" ARGUMENT
The built-in spring pulls the door shut behind everyone—kids, guests, even the forgetful spouse. Works on interior doors, garage entries, and exterior gates.
✓ STAYS OPEN WHEN YOU ACTUALLY NEED IT
Push the door past 90°—the hidden positioning ball locks it in place. Carrying groceries? Moving furniture? The door waits for you.
✓ HANDLES HEAVIER DOORS WITHOUT LOSING POWER
Adjustable spring tension means you set the closing force for your specific door. Light bathroom door? Dial it down. Heavy garage door? Crank it up.
✓ INSTALLS IN 15 MINUTES WITH BASIC TOOLS
Comes with mounting screws for both wood and metal frames. No special skills needed—if you can use a screwdriver, you can install this.

Frequently asked questions
Will this fit my existing door hinge holes?
Dimensions are 4" x 2.5" (100mm x 65mm) with standard mounting hole patterns. Most interior and exterior doors in US homes use this size. Measure your current hinges before ordering.
How strong is the spring? Will it close my heavy garage door?
The spring is adjustable—you control the tension. It handles standard interior doors easily and works on heavier exterior and garage entry doors when properly tensioned.
Do I need to replace all my hinges or just one?
One Shutlok™ hinge on a 3-hinge door is usually enough to create self-closing action. For heavier doors or stronger pull, use two.
What tools do I need to install this?
A Phillips screwdriver or drill, and a small Allen wrench (included) to adjust spring tension. Installation takes about 15 minutes.
How to use
- Step 1: Remove one existing hinge from your door (middle hinge recommended).
- Step 2: Align Shutlok™ with existing holes and secure with included screws.
- Step 3: Use the Allen wrench to adjust spring tension—clockwise for stronger closing force.
- Step 4: Test the door. Push past 90° to engage hold-open. Release for auto-close.
