    Customer Reviews
    Command™ Decorative Knob, Square is rated 4.7 out of 5 by 87.
    Rated 4 out of 5 by from Easy to hang something This was so simple to use to hang up something. My kids have lots of art they have made over the years and I have a display board where I can switch it out easily. This also has not removed any pain from the walls, when I removed it.

    Rated 5 out of 5 by from Doesn’t look like a 3m knob Have a work bag hanging on this at my office. I hang my bag there every day and it has been up for years and still looks great. Nice enough to be up and visible in a nicer office without actually costing a lot or being difficult to install.

    Rated 4 out of 5 by from Lovely for the Decor This was a free sample. It took me a while to find a place to use this knob. It doesn't hold much weight, so I have it holding up a foam-board sign on the wall of my sun room.

    Rated 5 out of 5 by from A place to park my pack! I received this product from 3m in exchange for an honest review. I love this hanging knob! Its square shape keeps the strap of my backpack purse from slipping off easily. It was a little confusing to apply at first, because it is in two pieces the instructions weren't very clear on how the knob locked into the base. I adhered mine to the side of a bookshelf, and let the adhesive "cure" for about an hour before using it. That was a month ago, and I've been hanging my pack there ever since. It usually weighs in at about 15-17 lbs (I weighed it daily while testing this product). The knob has reliably supported my bag every day since applied without failing. I have not tried to remove it, because I love it where it is.

    Rated 5 out of 5 by from Fantastic for showcasing! I got this product as a free sample from 3M and used it to keep my sash and tri-corn hat above my mirror in my bedroom. I never have to worry about my hat falling down because of the large surface, and it also holds little accessories like necklaces and sashes. It's pretty great and my only regret is that I did not buy it sooner!

    Command™ Weight Reference Guide

    Not sure which Command™ Product is right for you? We weighed some common household objects to give you a better understanding of the amount of weight you’re hanging on your walls. Explore our Command™ Weight Reference Guide to find the best Command™ Product for your project.

    • 1 lb. Hold

      Even the lightest items need the right support. Next time you brew a pot of joe in the morning, remember that a 16 oz bag of coffee beans is the equivalent to one pound.

    • 3 lb. Hold

      Comparing apples to oranges might not be a fair matchup, but comparing a bag of apples to your next project—that’s a different story. Did you know that a standard bag of apples is equal to three pounds? How do you like them apples?

    • 5 lb. Hold

      You want a damage-free hanging solution that’s up for the task—not one that will drop your object like a hot potato. For items with a bit more weight, remember that five pounds feels just like a standard bag of potatoes. Unsure whether you have a standard size bag? Just check the front of the bag for the 5 lb weight.

    • 8 lb. Hold

      Looking for a solution to hang your heavier objects? No there’s no use crying over spilt milk. Just reach for the gallon of milk in your fridge—it weighs about eight pounds.
