A new class of collimators has been designed and built for the PEP-II collider which has opposing movable jaws. These collimators are designed to reduce backgrounds in the BaBar detector. They can support several kW of synchrotron radiation power striking the jaws or the impedance matching ramps. There are no longitudinal nor transverse higher-order-modes. The jaws and collimator body are made of Glidcop.
