Product Details
- 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 classification
- Precision contoured wedges provide proper contact and support of the PVC pipe wall, each wedge is manufactured with an elongated contour that evenly matches the outside circumference of each nominal diameter of PVC pipe
- Wedge actuating bolt provides the installer with two visual torque indicators, the breakaway top and secondary shoulder stop ensure proper engagement of the wedge segment at the time of installation
- Features a non-corrosive, two-piece ABS plastic spacer that is removed when using the product to restrain IPS sized pipes meeting ASTM D2241, the two-piece design of this spacer allows it to be removed without requiring disassembly of the product
- Unique wedge segment and actuating bolt design allows the two components to interface using a cam action principle, allowing the wedge segments to rock and increase their grip on the pipe wall as thrust on the assembled joint increases
- Allows improved resistance to subsidence, seismic forces, and other movement within the maximum deflection limitations of the mechanical joint under applicable AWWA standard
