Better belt tensioners?

Has anyone designed some ‘better’ belt tensioners? I have some slack in my X belt but I’ve lost count of the number of cable ties I’ve broken at the opposite end of the belt to the one I’m trying to tighten, it’s starting to get a little tedious :frowning:

There are other tensioners out there but I have a feeling something else is going on. The zip ties are rated to 40+lbs and we only need less than 10lbs. I have snagged tools on the belts and had them ripped out of my hand and never broken a zip tie. The LR has a very smooth tie path.
