This is the E-Z Slide for the Hybrid Pro, and Pro Rage, with the M61 ends installed, (Anchors available, but not included, see below). The E-Z Slide offers more mobility, and provides more freedom to turn your head over the standard tether sliding system included with the Hybrid Pro, and Pro Rage. It is available in different lengths, and is usually purchased after a customer receives his restraint and adjusts.
Once the original tether is adjusted, you can measure for the E-Z Slide by measuring your original tether from end to end of the webbing, with the tether laid flat. This measurement you get will be the measurement you need to order. Since this is the E-Z slide for the M61 anchors there is not adding or deducting for the proper measurement.
See below for Helmet Anchors.
