The MSKT is an energy-absorbing tangent terminal that is MASH TL-3 compliant. MSKT has an overall length of 500 and has eight posts spaced at 63 on center. During head on impacts, the MSKT head slides over the W-Beam guardrail, sequentially kinking the rail. The rail then exits the head and the vehicle is brought to a controlled stop.Highway Guardrail & Posts | GSI Highway ProductsGSI carries an extensive inventory of highway guardrail products including 10 gauge and 12 gauge material.
