Since one of the complaints about the Super Grip Lock was that it was too small I will preface these instructions with the fact my deadbolt and doorknob are not far apart. It’s about 5 1/2″ center to center. If your deadbolt is much farther, just cut longer pieces of Velcro to fit your door.
The last time I checked Joann sells 1 yard packets 3/4″ Velcro for $.99. Wherever you get it, a yard is more than enough.
Constructing the security strap
My deadbolt turn knobs are like an arrow — a flat end and a pointed ended. The flat end is bigger than the pointed end. I measured and a pocket inch high would be perfect for the flat end. Check your deadbolt knobs to see how big a pocket you need.
All sewing should be double stitch or tight zigzag to make sure it’s strong.
- I cut 2 2″ strips of 3/4″ Velcro hook (the stiff side) and sewed them together so it was approximately 2″ by 1 1/4″. This is the pocket.
- Sew a 24″ strip of 3/4″ Velcro hook centered on one end of the pocket with the hook on the pocket and the 24″ strip facing the same way.
- Fold the pocket lengthwise in half with the hook facing out. Stitch both sides of pocket.
- On then end of the 24″ strip opposite the pocket fold 8″ back with the hook side facing out and stitch together.
- Cut a 16″ strip of 3/4″ Velcro loop (the softer side) and sew it to the end of the hook strip opposite the pocket that you just sewed double. The loop should face the same way as the open pocket.
Using
1. Attach the pocket on the deadbolt knob to the end that applies pressure (pull the knob toward) to the locked position.
2. Wrap the strap around the turn knob again.
3. Go down and around the doorknob. Wrap back up and around the deadbolt turn knob and down the other side toward the door knob.
4. Pinch the strips running between the doorknob and the deadbolt together to hook the Velcro.
Testing
After I did one of these I had the door open with the deadbolt thrown and tried my key. I would have bent the key before the deadbolt would turn. I was happy 🙂
I’m going to make a third one, probably longer, to throw in my bag when I travel that will hopefully work on hotel door deadbolts as well as these do at home.
My wife and I love them!!
We ordered them online and gave 2 to my sisters, my son and 3 daughters. They love them too.

Added security is always a good feeling. What a nice gift to give your family members!
Thank you so much for sharing this!
I was so excited to find this, as hubby is working away for a few weeks. I thought I understood the instructions. No such luck. I can’t figure them out for the life of me. 🙁
Try looking at this video and see if that helps https://www.youtube.com/watch?v=cS6hxAuBarQ. Send me questions and I’ll be happy to answer.
Our deadbolt knobs are horizontal in the “thrown” or locked position; I assumed all were. Did you somehow modify yours to be vertical?
It shouldn’t matter whether is horizontal or vertical. See the picture on this link:
I’m sure you are right as far as function of this Super Grip Lock is concerned – I just was curious about the orientation, assumed that all were unlocked when the knob was vertical, locked when horizontal. That’s been the case in every house I’ve lived in.
I checked images in a google search and I think it varies depending on the maker of the dead bolt.
Hey
I have just have the deadbolt and not the knob. Any ideas on how I can still use this ??If you can get back to me ASAP that would be great.Someone has been breaking into my room and fucking up my things.
Thanks !
I sent you an email.
