The PRO Campstopper plug is a bigger model than the CAM model. It uses the same patented, innovative system for plugging pipes featuring a locking handle, but is more suitable for bigger pipes with nominal bores ranging from 175-mm to 500-mm. The PRO model is ergonomic and easy to insert into pipes. It can hold back up to 0.5-bar pressure and is fitted with an 80-mm wide joint. The construction is to the standard of EN-6811, and includes aluminum and EPDM that is WC-grade. The lever actuated plug is ideal for temporary plugging of rainwater and sewage pipe networks. A 1-inch bypass is fitted, which allows the plug to divert flows and maintain the water flow. A cord can be attached to the handle so that the user can withdraw the plug remotely after use.
