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.
