These are terrible! What I did was grind down the retention slot where the spiked bar rests (to allow the belt to slide past) - as well as tap the buckle to crush the thickness - the goal to apply more pressure/friction to the belt. It was (and still is) not a perfect fix. These are just poorly designed where avoidance is more advisable than repair/fix/remedy. Terrible reviews - if you own one, sorry...and good luck.

Every Carhartt product I've owned in the last ten years has failed before what I would consider a reasonable service life. The quality just isn't there anymore.

I feel like accessories like this are just outsourced crap with their logo on it.
