If you need to cut the barrier down then you need a 9" angle grinder with metal cutting blades, plus a drill with 16mm metal holesaw if you need to re-position any fixing holes in the beam – and if you’re using dig-in posts you’ll need digging equipment such as post hole shovels and concrete to secure the posts.
