Description Halkey Roberts Cylinder Retention System for Lifejackets. Halkey Roberts developed the cylinder retention system as a unique and low cost solution for retaining the CO2 cylinder. Historically the lifejacket industry has had a problem with Gas Cylinders coming lose in wear. Wearers often neglect to check regularly enough and a failure to inflate is an increased risk. Simply fit the device over the nut on the front of the inflator. A retaining ring grips the cylinder tight to the device helping prevent the CO2 cylinder becoming loose during use. The system is currently designed for all CO2 sizes, but can be a tight fit with larger CO2 cylinders such as the 60g. The backplates come in two versions. V90139UCH is for mostly left hand pull devices. V90139CH2 is mostly for right hand pull devices. However if you have one of the rare Hydro Inflators in your jacket, these are reversed. Full details are available here and if in doubt, please get in touch. NB. BE CAREFUL! A jacket might have an inflator on the left hand side of the jacket that might still be left hand pull (and vice-versa) Left hand pull and right hand pull refers to the placing of the pull toggle on the inflator as you can see on the link to the information just above. It is suitable for most Halkey Roberts inflators.
