A recent report on Delaney Hall, an immigration detention center in Newark, described the facility as being surrounded by chain-link fencing crossed with razor wire. The image is useful because it reflects a common perimeter-security approach: the fence provides the boundary, while the wire above it adds another obstacle to climbing.

For correctional facilities working with an existing chain-link perimeter, Razer Barbed Wire can provide that additional layer without replacing the entire fence.

Keep the Existing Fence. Reinforce the Top.

Chain-link fencing is widely used because it is economical, flexible and relatively easy to install across large boundaries. But its open structure also means the upper section needs additional protection when a higher security level is required.

Razer Barbed Wire can be installed along the top of a suitable existing fence to create a more difficult climbing route.

The upgrade can be concentrated on the areas that matter most:

Main outer perimeter

Restricted compounds

Service-side boundaries

Areas alongside roads or open ground

Sections requiring additional climbing deterrence

This makes the product particularly relevant to prison fence upgrades, rather than only new-build projects.

Choose the Wire Configuration Around the Fence

Razer Barbed Wire is available in concertina, straight, cross and flat configurations, giving security planners more flexibility when matching the barrier to the existing fence.

A concertina arrangement can provide wider physical coverage along the upper perimeter, while flatter or more compact configurations may suit areas where installation space is limited.

The core wire can also be supplied in galvanized or stainless steel, depending on the site's environmental and durability requirements.

A Straightforward Perimeter Upgrade

Replacing hundreds of metres of serviceable chain-link fencing can create unnecessary installation work and project cost. A reinforced upper section can address a more specific weakness.

If you are upgrading a chain-link prison or detention-facility perimeter, send us the fence height, total length and preferred wire configuration. We can recommend a suitable Razer Barbed Wire solution and provide a project quotation.
