These resources contain criteria for installing guiderail and information concerning what length, type, and end treatment of guiderail to install. WARRANTS The forces required to push the impact head down the rail are lower than other tangent end terminals. The impact head weighs less than 175 pounds. The high strength steel construction and lower impact forces results in a better performing design. The impact head is significantly easier to remove from the rail compared to competitive systems.
