The SRT™ 27 System is a straight flared, single-sided, re-directive, and gating end terminal. The SRT™ 27 System is a 27 3/4” [705 mm] high (measured from top of rail to finished grade) end terminal used to shield 27 3/4” [705 mm] high strong post W-beam guardrail.
 
This system is designed to reduce injuries to passengers upon impact and to minimize roll-over or perforation by the guardrail to the vehicle.
