Product Details

  • Restrained joint harness assembly for existing ductile iron pushon pipe bells, a split One-Lok wedge-action restraining gland is used to secure the ductile iron pipe spigot and connects with all-thread restraining rods and nuts to a two-piece back-up ring that seats against the ductile iron pipe bell
  • SSLDH allows for easy assembly since both the restraining gland and back-up ring can be rotated to provide easy and proper alignment of the restraining rods
  • SSLDH restrainer set is ideal for upgrades or tie-ins to existing ductile iron pipe systems as the two-piece wedge gland and back-up ring provide today's restrained joint technology to pipelines that were not properly restrained during their initial installation
  • Mechanical joint restraining gland that implements a series of individually activated wedges into the mechanical joint follower gland
  • ONE-LOK SSLDH precision contoured wedges provide proper contact and support of the ductile iron pipe wall
  • SSLDH 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
