Philadelphia Resins CHOCKFAST ORANGE is an epoxy based pourable compound that cures at normal temperatures to become an extremely tough and durable solid. CHOCKFAST was specifically developed for chocking marine main propulsion and auxiliary machinery and since its introduction in 1963 has earned the approval of the major classification societies worldwide.

The widely acknowledged superiority of CHOCKFAST chocks over those of steel or cast iron has led to their adoption throughout the world by ship owners and shipbuilders. Many thousands of ships with engines up to 70,320hp have logged millions of hours at sea with CHOCKFAST chocks.

Since the machining of foundations is not required and all machining and hand fitting of chocks is eliminated, the cost and time required for machinery installation are dramatically reduced.
Because of the full contact intimate fit of CHOCKFAST chocks to the mounting surfaces, fretting of the chocks and loosening of hold-down bolts are eliminated. Thus the original alignment may be retained indefinitely.
While the physical properties of CHOCKFAST ensure alignment, the compressive modulus is substantially less than that of steel, providing a mounting with decided advantages under shock loading and often much smoother and quieter operation.
