Example: A vehicle weighting 4000 lbs. would apply a weight to the surface of a Tuff Block Light® of less than 100 psi. The Tuff Block Light® is UL rated at 600 psi. ,a safety margin of 600%. But if the tire had a large stone stuck in the tread it could cause a failure of the glass structure. The stone has a very small surface area and could apply all the weight to a very small area of the block greatly exceeding the 600 psi. Rating. The odds of this happening are very small. Thus our claim “Virtually” indestructible.
