The specially roll-formed Impasse™ Rail is designed to be stronger than
conventional rails. Pointed security spikes along the top front surface
between pales prevent climbing.
The specially roll-formed Impasse™ "I-Beam" is designed to withstand
significant bending forces applied laterally in opposition to its major
axis.
STALWART ANTI-RAM SYSTEM
The specially roll-formed Impasse™ Rail acts as a tray for carrying a 1"
diameter steel cable that runs continuously from terminal to terminal in
an installed fence line. Multiple rails can be attached (at lower end of
panel) to carry multiple cables. With a two rail Stalwart cable system
integrated into the Impasse™ fence, a 15,000 pound vehicle traveling 40
mph has been stopped within 1 meter.
