Service line clamps hold the two pipes in place to ensure no external forces act on the pipe and couplings while the electrofusion process takes place. The service line clamps hold pipe sizes ½” CTS - 2” IPS. They come in a variety of configurations from multi-sized clamps, mini-clamps, reducing clamps, and vise-grip style clamps. The multi-sized clamp is dual-purpose and can be configured as a straight coupling clamp or a reducing coupling clamp. The vise grip clamps are designed for fusing couplings on the outlet of tees.
