Backset and faceplate compatibility

Faceplate dimensions are 230×16×3 mm and backset E is 20 mm. E is the horizontal distance from the faceplate reference to the cylinder operating axis and cannot be replaced by door thickness; faceplate width and thickness must also match the door-edge mortice.

Operating construction and selection

Uses a BAYONET bolt with 22 mm throw and a separate independent latch operated by an 8 mm handle spindle; Check the main bolt keep and latch position together.

This model uses an oval-cylinder interface; a Euro-profile cylinder cannot replace it merely because the length matches. When installing the open lock case, prevent frame-machining debris from entering the mechanism.

Limitations

• The diagram on this page explains only backset, not mounting hole positions; check the manufacturer's drawings for complete keep and connector dimensions.
• Product dimensions and construction do not establish a security grade for the complete door or certification for a particular application.
