Cam-Lock Joint Restraints
Smith-Blair Cam-Lock Joint Restraints save labor by providing superior restraint with fewer wedges and install on IPS size PVC without modifications. The Cam-Lock's lower bolt torque and wider wedges reduce pipe stress. Cam-Lock Features include color-coded nuts and wedges, epoxy coating, visible wedge engagement and longer T-bolts. Available in sizes 3" through 24".
Bell-Lock Joint Restraints
Smith-Blair Bell-Lock Joint Restraints provide a quick and efficent means of restraining hydrants, valves, pipe bells and fittings used in water and wastewater systems. Bell-Lock features include recessed shoulders for single wrench installation, compatible with standard MJ and some push-on style fittings. Available in sizes 4" through 12".
Pipe-Lock Joint Restraint Couplings
Smith-Blair Pipe-Lock Joint Restraint Couplings are fabricated steel sleeve restraint couplings that can be used to connect and restrain plain end pipe to plain end pipe.
Flange-Lock Flange Coupling Adapters
Smith-Blair Flange-Lock Joint Restraints restrain plain end pipe to plain end pipe and can join IPS PVC or ductile iron OD PVC to ductile iron or carbon steel.
AWWA M-11 Style Harness Assembly
Smith-Blair Harness Assemblies should be used where calculations show the forces resulting from a lateral connection, change in direction of the pipeline, unstable soil, thermal expansion/contraction or other service conditions could cause the pipe to move out of the coupling.
Smith-Blair Anchor Studs are designed as an alternative coupling method to harness assemblies for applications where moderate longitudinal stresses are encountered.
EZ-W Restraint Couplings
Smith-Blair EZ-W Restraint Couplings for water service are designed with push on gaskets and engineered to simplify installation, restrain the pipe joint and ensure a tight seal. EZ-W Couplings can be used to connect IPS PE to steel pipes 1" through 12" diameters and ductile iron to IPS PE, PVC or steel pipe, 3", 4", 6", 8" and 12".
