The ONE-LOK Series SSLD is a mechanical joint, wedge-action restrainer gland constructed in a split gland configuration for use on existing installations of ductile iron piping systems. The two halves are fitted over the pipe and bolted together to provide thrust restraint to a joint that has already been installed, such as in a pipe repair situation. The ONE-LOK SSLD is currently availible in sizes 4-12" and is rated at 350psi.
