You can get a pair of bolt cutters for under $50 USD.

Chain link fences are attached to the posts with tension bars. This is basically a strip of metal that runs up through the links and is held to the post with a tension band that wraps around the post. If you need to, you can also cut through the tension bars using your bolt cutters, though in most cases it’s easier and makes more sense to cut through the links of the fence. You can also use this method to cut off excess chain link after installing a new fence. For instance, to shorten the height of the chain link so that it matches the top rail instead of extending above it.

The bolt cutters will make quick work of cutting through the links. After you have cut through them all, you can easily separate the chain links from the rest of the fence to remove or replace the section.

If you cut each link in the middle, on the straight part, it will be more difficult to separate the pieces of fencing.

If you are replacing a damaged section of rail, then get a replacement rail first and measure it to know exactly how long a section you need to cut out from the damaged rail. You can also use this method to shorten fence posts that aren’t installed yet. In this case, measure each post you want to cut carefully so you can cut them all to the same length.

It’s a good idea to have an extra blade handy, in case the one you use becomes dull and difficult to cut with.

Always wear this type of protective gear when operating any power tool.

Most reciprocating saws have a handle at the back with the power trigger and another grip at the front near the blade that allows you to guide and control the saw while cutting. It’s a good idea to wear work gloves when using bolt cutters to protect your hands in case of any accidental slips. Wear safety glasses for eye protection as well in case any tiny pieces of metal fly into the air.

Reciprocating saws are very heavy-duty and will do most of the work for you, as long as you have a sharp blade.
