The Sigma One-Lok Series SLDEH Ductile Iron Pipe Joint Harness Consists of Series SLDE Mechanical Joint, Wedge-Action Restraining Gland Installed on the Plain End of the Pipe Joint and Incorporates High Strength, Low Alloy, Corrosion Resistant Restrainer Rods Connected to a Standard Mechanical Joint Follower Split Gland Behind the Shoulder of the Bell End of the Pipe Joint; The Sigma Two Piece Back-Up Ring Series Sg has Oblong Ears to Accommodate Varying Outside Diameter of Di Pipe Bell; The Sigma One-Lok Series SLDEH is a Mechanical Joint Restraining Gland that Implements a Series of Individually Activated Wedge into the Mechanical Joint Follower Gland; When the Wedge Segment is Engaged by the Actuating Bolt the Primary Contact Edges of Each Wedge Segment Lock onto the Pipe Wall; This Action Causes the Primary Contact Edges to Grip the Pipe and Effectively Restrain All Classifications of Ductile Iron Pipe; One-Lok SLDEHS Precision Contoured Wedge Provide Proper Contact and Support of the Ductile Iron Pipe Wall; Each Wedge is Manufactured with an Elongated Contour that Evenly Matches the Outside Circumference of Each Nominal Diameter of Ductile Iron Pipe; This Elongated Contour also Eliminates the Concern of Damage to Both the Pipe Wall and the Interior Cement Mortar Lining Caused by Point Loading, Even on the Thinner Pressure Classes of Ductile Iron Pipe; One-Lok SLDEHS Wedge Actuating Bolt Provides the Installer with a Visual Torque Indicator; The Breakaway Top Ensures Proper Engagement of the Wedge Segment at the Time of Installation; Unlike other Actuating Bolt the One-Lok SLDE is Manufactured with a Proprietary Quality Control System that Ensures the Breakaway Tops will Activate at the Correct Torque; The Breakaway Top is Sized to Match the Same Dimension of the Bolt and Nut Used to Assemble the Mechanical Joint Fitting and Follower Gland, Eliminating the Need for Special Installation Tools; Once Engaged the Actuating Bolt Leaves a Residual Hex-Head Shank, Allowing Post-Installation Disassembly of the Restrained Joint, if Necessary
