STEP 1 - Determine which fasteners your equipment needs, if any:

For each piece of equipment you need to secure, you will attach the security cable to that equipment with one of the following methods:

Some equipment already has a 'built in' way to attach the cable.

Take a look at your CPU. Does it already have an external 'hole'? This could be on the top or the back. If it does, you can run the cable directly through it, eliminating the need for a fastener.

The 810 lock style has a hole in the lock to allow you to form a second loop in the cable at the lock end, as shown here. The 820 lock style does not have this hole, so if you choose the 820 lock style, you can only use this method of attachment if you don't need the cable's built-in loop to attach to the desk (see step 2).

WARNING: MAKE SURE the stand is permanently attached to the monitor, otherwise, this method will not work. Some monitors detach from the stand with a push of a button or a couple screws and this would NOT be secure.


The SCISSOR CLIP fastener method.

This method uses the built-in security slot that is located in just about every type of equipment nowadays. This small rectangular cutout (about 1/4" long) is built into the equipment by the manufacturer for just this reason. It will sometimes have a picture of a padlock next to it, and it can be located just about anywhere! Each manufacturer and type of equipment has it located in a different spot! They don't make things easy sometimes :).

Take a look at the pictures below to see some of the locations of the security slot.

These are by no means the only locations these slots can be, but it gives you an idea of what to look for.

Once you have located the security slot, you can determine which method is best for security.

You can use external scissor clips (or X-clips as they are sometimes called). You insert the scissor clip into the security slot, then run the cable through to keep it closed. Or you can choose the 820 lock style with the scissor clip directly built in! This works great for the last piece of equipment you are securing with the cable, and can be much more convenient.

Most people need a combination of both types...

The GLUE-ON fastener method.

This method permanently glues a fastener onto your equipment. This is used when there is no security slot or external hole to run the cable through. This method is also used when you want a higher level of security than the security slot provides. The glue-on fastener footprint measures 2 3/4" x 1 1/8" and is 1" high. It can withstand over 2,000 lbs. of pull force.

Although 90% of all equipment today has a built-in security slot, including printers, scanners, projectors, flat screen TV's, etc. there are still some that don't. The glue-on fastener can be used to secure ANY equipment! (this is a permanent attachment)
