Product Details

  • The Sigma ONE-LOK™ series SLDM modified wedge-action mechanical joint restraining gland is suitable for use on pit cast grey iron pipes with oversized C and D barrel dimensions, for pit cast pipes with A and B size outside diameters per AWWA C150/151, the standard ONE-LOK Series SLD or SLDE restrainer may be used without any modification
  • SLDM is a mechanical joint restraining gland that implements a series of individually activated wedges 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
  • Precision contoured wedges provide proper contact and support of the ductile iron pipe wall
  • 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 bolts, the ONE-LOK SLDM 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 dimensions of the bolts and nuts 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
