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.
"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).
vRigger requires the Microsoft Windows operating system. If you want to run vRigger on a Macintosh computer, you will need to install the Windows operating system on your Mac. This can be done various ways, including using a program named Parallels. You can then run any Windows program on your Mac.
The instructions on this page provide general instructions on installing Parallels, Microsoft Windows, and vRigger on your Mac. Installing Parallels and Windows isn't overly complex, but it isn't easy. For additional assistance, please visit Parallels.com.
Parallels allows you to run Windows on your Mac. It's a bit complicated to setup, but it is very cool to be able to run any program on your Apple computer.
Parallels does not include a Windows license, so you'll need to purchase Microsoft Windows. When you purchase Windows you'll receive a DVD (or a downloadable "iso" file) and a product key. You can purchase Windows from Microsoft.com and from many online stores.
Purchase Parallels from Parallels.com. This is the software that lets your Mac computer run both the Windows and Macintosh operating systems (there are other programs that do this, too). If you need help with the Parallels software, please visit the Parallels support page.
Download and install Parallels on your Mac.
After installing Parallels, you'll be prompted to install Windows from a DVD or image file (an "image file" has the file extension "iso"). Select the DVD or image file to install Microsoft Windows.
You should confirm that Windows is working on your Mac before you purchase vRigger. (We'll certainly refund your money if you are unable to run vRigger on your Mac.)
When displaying vRigger.com from within Windows (step #5), click the Ordering link and then purchase vRigger.
Follow the downloading instructions that are displayed immediately after placing your order. You'll be prompted to enter your vRigger license key during this process. After entering your license key, you'll be prompted to check for, and to download, the rigging gear.
If you need additional help with Parallels or Microsoft Windows, please visit Parallels' support page.
For help with vRigger, please visit the vRigger Learning Center.
