Sentry Thrie-Beam Guardrail

Sentry Thrie-Beam Guardrail has advanced the containment level of public domain thrie-beam guardrail by introducing innovative technology into the thrie-beam guardrail release mechanism.

The additional corrugation provided by the thrie-beam rail combined with the higher mounting height, stiffens the barrier and improves its ability to contain larger vehicles.
