This tripod hook is a simple solution for attaching the new Trimble TSC3™ or Spectra Precision Ranger 3 controller to an instrument tripod. Made of strong stainless steel, the 5196-18 is designed to fit precisely on the back of the controller with or without the unit's hand strap in place. Install or remove the clip easily with a #1 Phillips screwdriver. Works with most heavy-duty total station-grade tripods that feature a connecting bar on the hinge area.
