This also applies to cable, chain, and webbing.

Gear that is anchored includes anchors, rocks, trees, tripods, trucks, etc.

A "bight" is a simple loop in a rope that does not cross itself.

A "bend" is a knot that joins two ropes together. Bends can only be attached to the end of a rope.

A "hitch" is a type of knot that must be tied around another object.

"Descending devices" (e.g., ATCs, Brake Bar Racks, Figure 8s, Rescue 8s, etc) create friction as their primary purpose. The friction in descending devices is always considered when calculating forces.

The "Safety Factor" is the ratio between the gear's breaking strength and the maximum load applied to the gear (e.g., 5:1).

License Keys

You will receive a "license key" when you purchase vRigger. Your license key will be displayed on the screen immediately after you place your order and it will be emailed to you.

Your license key "authorizes" vRigger to run on your computer. It also controls which rigging industries are licensed. You should not share your license key with other people or you will not be able to run vRigger.

The first time you run vRigger, you will be prompted to enter your key. You must be connected to the internet so your license key can be verified.

Each vRigger license allows you to run vRigger on one computer. The license also allows you to run vRigger on a second computer (e.g., a laptop) if vRigger will be used by the same person.


Maximum number of installations

If a message states that "vRigger has been installed the maximum number of times," your license key has already been used.

This often happens when you are moving vRigger to a new computer. If you still have access to your old computer you can unlicense it. Otherwise, please contact us and request that we reset you license key.

Problems with internet connections

After entering your license key, vRigger may mistakenly report that you are not connected to the internet. This is almost always caused by a firewall or proxy. If vRigger continues to display this message and you can connect to vRigger.com using a browser, please contact us (be sure to tell us the exact message displayed by vRigger).

Lost license key

If you are reinstalling vRigger and are unable to locate your license key, please contact us and request a replacement key. Be sure to tell us the name and email address you used when you purchased vRigger.
