Powerhouse, an online store for engine-builders and automotive machinists which provides tools and measuring instruments that offer precision and durability, has released its Retainer Degree Gauge Tool. Users can quickly and easily identify the valve retainer degree to avoid mismatching parts that could lead to valve failure. With the Powerhouse Retainer Degree Gauge Tool, there's no more guessing which valve locks to use with retainers. Manufactured in the USA from high-quality aluminum, the tool precisely measures the degree of any steel or titanium retainer. It is able to measure 6 , 7 , Super 7 (8 ), and 10 valve retainers and is anodized for added durability and long life. Plus, to aid in the identification, each angle is laser etched for easy visibility. For more information, visit www.powerhouseproducts.com, or call 800-872-7223. (Content courtesy of Powerhouse)
