The 6 series centerline strikes are available in standard profile or low-profile options to accommodate different latch projections. This heavy-duty series combines several requested key features. Standard features include a multi-voltage single solenoid, selectable lock mode (no tools necessary), horizontal adjustment, and plug-in wire connectors. 1/4" Horizontal adjustment makes installations faster and easier. Plus, with the RCI 6 series, there will be less pressure on installers' strike inventory because these RCI strikes do it all.
