Standard Centering Cradles are used to center the pipe in the end of the casing, making it easy to install TDW Z-SEAL™ Casing Seal. The cradles also carry the weight of backfill dirt and insulate the pipe from the casing. They are recommended for use with TDW Concentric Support Insulators. Nonconcentric 3-Way Cradles restrain pipe in all directions. They are used with U-SEAL™ Casing Seals.
Concentric Support Insulators feature larger
support runners at the bottom to center the
pipe inside the casing. Ample clearance is allowed by the smaller runners to permit free movement into the casing. Cables and runners are nonconductive. This insulator is easily installed using either a speed wrench or ratchet.
