PETINCCN TPU Dog Training Collar Strap - Replacement Belt for PET998DRB/PET998DBB/998DR/998DB/PT0X1/PT0Y1/PT0Z1 Shock Collars - Durable & Adjustable Black Dog Collar Accessory - Perfect for Outdoor Training & Electric Fence Systems

Very strong. Been using them for a few months with no issues.I bought these as a replacement for my two shock collars and they fit around a standard size shocker, itself. I just cut off the excess collar to fit my dog perfect!Our first one lasted about a year and that was almost every day use including 30+ days through heavy brush. After that they start to fall apart. Not bad though, that's just one of those things you factor into having a great hunting dog.Really love the collars very durable and able to cut to sizefits electronic collar perfectlyLove it. Just like I expectedI needed something to attach to my dogs ecollar that would keep it snug enough to actually work. These are great! They will work for any size dog too as the holes go all the way through out the collar and it’s super long. You get 2 and the price is better than most that you only get one in.We needed more durable staps for the training collars we use for our two Rottweiler pups. These were perfect & really helped because we can now tell them apart by looking at their collar.
