Locking Dog Assembly

Locking dog assemblies are integral components of the complete tool system for the PISA® family of anchors, which also includes the kelly bar adapter, torque indicator, and drive end wrench. Designed for compatibility with different sizes of kelly bar adapters, the C3030069HD and C3030069HDN models fits 5-1/4” bolt circles, while the C3030981 model is suitable for 7-5/8” bolt circles. The ring style adapters feature three distinct ring positions for versatile functionality: the inside ring secures both the drive end wrench and the Pisa rod, the middle ring releases the PISA®rod while holding the drive end wrench, and the outside ring releases both the Pisa Rod and the drive end wrench. The C3030069HDN assembly has a lever handle that is used for the same functionality. This flexibility allows for precise control and efficiency in anchor installation processes.
