Replacement concealed overhead door closers and parts to suit Ryobi™ 30 series closers in aluminium commercial doors. The range covers door weights up to 70 kg (30-2x models), 110 kg (30-3x) and 170 kg (30-4x), each with a 90° or 105° opening and with or without hold-open. The arm channel, adjustable side loading arm, side loading arm fixing pack and floor pivot assembly are sold separately, so a single worn part can be replaced without changing the whole closer. Before ordering, check the model number on your existing closer, the weight of the door and whether it needs to hold open.
