Shunyata Research’s SR-Z1 Outlets, are built by Hubbell to Shunyata Research's exacting specifications. These outlets have large internal contacts that provide superior contact integrity for power cords. All Ferrous metals have been removed from the SR-Z1 design, as have carbon materials, which Shunyata's independent tests have proven are detractive to optimal AC performance.

Additionally, the body of the outlet is oversized, providing improved internal cooling capacity when under heavy current loads. All SR-Z1 outlets undergo Shunyata's proprietary Alpha Cryogenic process. This unique cryogenic treatment is performed on-site at Shunyata Research's factory, and has proven superior to any other cryogenic treatment type that Shunyata Research has tested.

The SR-Z1 outlets provide a critical contribution toward the award-winning performance of Shunyata's Hydra and Guardian Series power-distribution products.
