Introducing BackZone 35 (250-1903-BZ35), Rostra’s latest addition to our comprehensive line of vehicle parking assistance systems. Designed around the durable components that comprise our BackZone 35 system, BackZone 35 expands the usefulness of that system by adding an extra 10 feet to the sensor extension harness and a more powerful control module. Key features of this system include the following:
Smaller Audible/Visual Display
Compared to Rostra’s standard BackZone Plus and FrontZone parking assistance systems, the BackZone 35 includes a dashboard/visor mount display with a smaller overall footprint designed to more seamlessly blend into a vehicle’s interior.
35-Foot Truck Harness
BackZone 35 sensor-to-module wire harnessUltrasonic parking assistance systems typically require the use of harness extensions when being installed onto light or heavy-duty trucks. These extensions can introduce multiple points of failure and interference. That changes with BackZone 35. Each BackZone 35 system includes a weather-proof 35’ harness designed to connect the four bumper-mounted ultrasonic sensors to the BackZone control module in a single run.
BackZone 35 Control Module
BackZone 35 contorl module with advanced object detectionThe BackZone 35 control module is specific to this particular parking assistance system and includes an internal electronics redesign necessary to transmit interference-free signals from the bumper-mounted ultrasonic sensors along the 35-foot harness.

Keeps the doggo happy
Size: Large, Style: Crinkle Fry
I had to replace my bully’s previous french fry. It’s great for strong chewers but will not last forever. It will deteriorate and as a result can cut doggo’s mouth. It’s his favorite toy.

Very Hard & large toy
Size: Large, Style: Crinkle Fry
Harder and made from a different material than the other bark toys I have purchased. I think the others are nylon. Very durable just not as satisfying for the Cane Corso to chew as the more flexible toys. Was larger than I expected.

great for destructive chewers
Size: Large, Style: Crinkle Fry
it is so hard to find a dog toy that won't get destroyed within a week at most, esp with easily bored of toys dogs.
LUCKILY! i will say that both my goldens enjoy the french fry. i have an old picky dog and a young violet chewing dog. the only downside is i wish if i got 2 they wouldnt fight over the one the other has, but that's a review on my dogs more than anything lol
I was looking specifically for a barbox super chewer that is low on cost without losing quality of toy. 5/5 got exactly what i needed! that toy is STRONG and holding up great!!

Great toy for tough chewers. Just don't expect a miracle!
Flavor Name: Bacon, Size: X-Large
This is a great option for tough chewers, although if your dogs are anything like ours, there is a procedure to ANY new toy no matter how "tough". If I gave them this Nylabone and they went unsupervised day one, they would wreck it and it'd be in the trash within the hour. I say this to tell you, if you have a top 10 bite strength aggressive chewer, that you shouldn't expect a miracle.
If instead, I give it, take it away when they are working it too hard or being particularly destructive, and then give it back- and do this a few times for a week or so, then they'll chew it in a less aggressive fashion- they'll enjoy it and it lasts a long time. I don't know what it is about the first few days, but when something is "new" it has to be destroyed.
When it's been in the house a few days, they are rough but not as bad. Like the ones listed "virtually indestructible" will last 6 months as long as we have multiple around. It will show damage, there will be shrapnel in the carpet that will scratch up your feet, but it'll be worthy of play still. I consider 6 months in our house worthy of 5 stars.
This has been true for 2 Dobermans and a German Shepherd- and all of them have proven ability to destroy these products day 1 if I don't behave appropriately on introducing the new toy. If your dog wrecks these in the first 10 minutes, I'd say you probably need to work on supervising new toy play, and taking it away when they become to aggressive. This is a training issue, it can be done!

Durable, almost nondestructable, exelent guality bone.
Flavor Name: Bacon, Size: Medium, Flavor Name: Bacon, Size: Medium
We bought these bones about fifteen years ago and now I've been looking for them and was not able to find them. I've almost given up hope that they're still on the market. We finally found them yesterday. Since then we only have one small left and after a long time of gnawing on it, our two 50lb Labrador/German shepherd puppies are arguing over it. Even though they have other rubber and plastic toys that are supposed to help their teeth and gums, these two have taken a liking to this small size nylon bone and literally fought over it. The are aggressively protecting it like it would be real bone. I can't wait for the new two durable nylon bones to arrive. They are great for their teeth and gums.
Thank you for continuing to make them.
