A rotatable bolt ring assembly is used to add bolt holes to a standard claw-clamp style Large-Flange™. An assembly consists of one aluminum bolt ring and one nickel plated spring steel retaining ring. The retaining ring fits into a groove on a claw-clamp style flange and holds the bolt ring onto the flange. Replacement retaining rings are also available separately.
