Today we are going to show you part number 8157DPS from Master Lock. What we have here is our Quantum 15 steel cable lock which is 6 feet long. A couple nice features about this is a braided steel cable that would resist cutting or sawing. It is vinyl coated so it protects from scratches on delicate surfaces. The cable itself is actually 9/16 inch thick. Now we will show you the typical application of how you would use it. To operate it is pretty simple you will the key and turn it to pull it apart. Now that it is apart you can put it around your object and put it back together. Pull the key back out and it is safe and secure. Now we will show you the typical application by chaining this bike to a post. There you go your bike is securely tied to the post. As long as the post does not go anywhere your bike will not go anywhere. There you have it for part number 8157DPS from Master Lock. The 6 foot Quantum 15 steel cable lock.
