Sentry® Tubular Fencing System

Sentry® | Security Fencing

Tubular round bar security fencing

Image Gallery

The Sentry® security fence range of fencing and gates feature a welded semi pale-through-rail construction to combine style with performance and is equally appropriate for contemporary or more traditional settings. Like our Barbican® system, all Sentry® Fencing and gate panels incorporate concealed fixings for strength and security.

At Jacksons we believe that high security and safety are not mutually exclusive. That is why pales are spaced to a maximum gap of 100mm to conform to Building Regulations for anti-trap, making Sentry safe for applications where children may be present.
