Wedge action restrainer gland

SIGMA’s One-Lok Series SLDE wedge action restrainer gland for 54-, 60-, and 64-inch ductile iron pipes can serve as a way to reround large diameter pipes in the field. Larger ductile iron pipes are susceptible to shift in transit and handling, often requiring the use of hydraulic jacks on job sites to restore full roundness and specificity prior to installation. The product provides additional areas to the gland body that contain two sets of three jacking bolts positioned 180 degrees apart.
