Includes one black powder coated straight flat-faced 4ft extender and 8 black screws.
These extenders have two flat mounting plates to mount to a flat surface. For example, to a wood fence or aluminum fence. They will gain you 4 feet of additional height after mounting. They also include a welded stop at the top to prevent fencing from sliding down the extender after installation due to weather or animal pressure.
Fence material (not included) is suspended from multiple extenders, creating an extended up fence.
