*The above ratings are the opinions of HammerTek Corp. and are generalizations that do not apply to all applications. HammerTek offers free trials for users to accurately determine application-specific performance of Smart Elbow deflection elbows, and encourages users to consider the total costs that may occur when an elbow fails. Costs such as elbow replacements, maintenance, equipment rental, cleanup, lost production, etc. all negatively affect the operations of a plant and its bottom line.
