4 Pcs 1 inch (25mm) Plastic Ladder Slider adjustable Lock Buckles, Plastic tension lock triglide, Plastic Replacement for Belt backpack strap adjuster replacement (Black)

These are sturdy clips and they perform as promised.

I bought these to replace a broken buckle on my son's Under Armour backpack. He carries everything in his bag and it weighs a ton. These have held up to the extra weight. About a month after I replaced the first one the second Under Armour buckle broke and I replaced that one too. The replacements have both held for over a month without issue. A easy cheap fix!

My kid brings a really heavy backpack for high school. Her backpack is more than 10 lbs. One of her buckles broke off. I used this for replacement. You have to sew on the strap, attaching to the top of this buckle. So far, so good.

These worked perfectly and 1 broke just as 1 did with an original of the bag purchased.Keep making these and continue to work on strength and make them stronger if possible.

Had an old broken Jansport shoulder strap on a backpack. Superglued the piece onto the strap and bonded it for 24 hours. Backpack is like new, and I’ve still got 3 left! Great deal.
