The specially roll-formed Impasse™ Rail is designed to be stronger than conventional rails. Pointed security spikes along the top front surface betweeen 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 continously 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.
