Typical prison fence styles have the following distinctive features:

Y-shaped posts: The top of the post is designed in a Y-shape, which is the most recognizable identifying feature, used to install and support the anti-climb system on top.

Top protection: Between or on top of the Y-shaped brackets, spiral cross razor wire (barbed tape) is typically added, forming a highly deterrent physical barrier.

Mesh panel structure: The mesh panels are often reinforced with a frame design, giving the entire mesh surface a sturdy, rigid structure. The mesh surface often features a V-shape or horizontal bends to increase strength.
