Proven Security 

Protecting the public with First DeFence no-climb security barriers 

Community Safety

First Defence Security Barriers have been used in several countries and all over the United States. This system provides security for Government Installations, Utility Resources, Prisons, Mental Health Facilities, Communication Facilities and even Zoos. 

Extended Warranty 

We use the finest materials and can offer vinyl and powder coating services as required. Our materials carry an extended five year warranty. 

Choice of Fabrics 

Our meshes come in 9 gauge, 6 gauge and expanded metal, which prevents cut-through. Materials are available in either galvanized or polyvinyl/powder coated finish. (Posts, rails and fittings are powder coated for durability, chain link is fuse bonded polyvinyl.) 

Did You Know That Gravity Can Affect Your Jails Security?

That's right, Gravity! It's gravity that makes First DeFence Security Barriers so effective. Our arched design uses the force of gravity to pull potential escapees off the fence. Their own body weight works against them. 

Furthermore, their ability to gain a foot hold decreases as they climb higher. Their legs become less effective, and the mini-mesh at the top eliminates handholds!

Proven Expertise

With over 500 installations throughout the world, First DeFence has a proven track record of staisfied customers and a wealth of experience that can be shared with you.
