The H.T. Runner is the perfect solution for High Temperature and High Traffic areas where anti-fatigue isn’t the primary objective. H.T. Runner is the same dependable surface that’s used on Weldsafe No. 447 but as runner- only product. As a high temperature solution, the specially formulated rubber has an extraordinarily high melt point for demanding welding applications. As a high traffic solution the textured rubber surface assures solid footing and can be used for semi-permanent installations with common mastics. 

  • Melt point of over 500⁰ Fahrenheit (200⁰ Celsius) designed for welding
  • Install for aisle ways in facilities or transportation vehicles
  • Available in 5/64" (2 mm) thick
