Razor wire provides the ultimate in security and safety for your property. When criminals see a fence topped with razor wire, they’ll think twice about trying to get into your property. Razor wire makes chain link fences virtually unclimbable; people will move on to easier targets when they see your razor wire.
If you’re in charge of a razor wire install, here are some tips to help everything go smoothly. Our biggest advice: be careful! Razor wire can cause sever injuries if you’re not careful, and needs to be handled accordingly.
Length of the razor wire
Before proceeding to the installation, you should first estimate the total length of the razor wire needed to cover the entire area of the fence that you want to equip. To get the total length of the wire you need the following measurements:


1.  Parallel wire length (PWL) which is the total length of wire placed horizontally above your fence.  These are usually composed of three wires placed on parallel lines with at least a 1 foot distance from each other.  To compute the total wire length for this, use the following formula:
Parallel wire length = fence perimeter length x 3
2.  Coiling wire length (CWL) which is the total length of the wire placed on the parallel wires.  Use this only if you chose to install the said coiling wires for added security.  Compute for the wire length as follows:
Coiling wire length = Coils per foot x fence perimeter x average length per coil of wire
As a result the total wire length needed in your installation will be equal to the combined length of the PWL and CWL.  Don’t forget to use feet in all wire measurements.
Install razor wire braces
Razor wire braces are usually placed on top of each fence pole tilted 45 degrees toward the outside of your property. This will make your fence nearly impossible to climb.
Install razor wires
You will need to install the parallel wires first.  To do this, take one end of your razor wire and attach it securely to a corner post brace.  Stretch your wire on a straight line and tie it to each brace until the entire perimeter is covered.  Do this two more times in order to complete the three-parallel-wire installation.
Then install the coiling razor wires by tying each coil onto the installed parallel wires.  Make sure that each coil runs from the bottom to the topmost parallel wire. Do this until the entire perimeter is covered.  Cut the razor wire on ends if needed.
A team of three to five would be advisable to handle this job.  While installing your razor wire, don’t forget to ensure your safety and the safety of those people working with you. Proper tools, protective gear and secured ladders should be used.
