A specimen grip for a test specimen that has an actuator for operating the grip remotely mounted and coupled to the grip through a tubular housing which provides for temperature isolation between the grip and the actuator. The grip is specifically adapted to be used in environmental chambers where the grip must operate in either high or low temperatures which can have an effect on the hydraulic actuator used in the grip and connected devices, such as load sensors. By maintaining the actuator on the exterior of the environmental chamber by having a pair of modules that are connected by a sectional connector, a grip can be installed through small ports in the environmental chamber. Once installed, the assembly permits viable operation because the actuator is temperature isolated from the chamber.
