Included Parts
The following components are included with your Corston mortice lock:
- Lock body x1: This is the main mechanism, designed to accommodate either a Euro cylinder lock or a thumbturn.
- Front plate x1: The plate that fits flush with the door edge, covering the lock body.
- Strike plate x1: The plate fitted to the door frame that receives the latch.
- Crosshead wood screws x2: Used for securing the lock body.
- Flathead facing screws x2: Used for attaching the front plate.
- Flathead wood screws x2: Used for attaching the strike plate.
Diagrams on page 1 illustrate these parts.
Tools Required
The following tools are needed for installation:
- Drill: For creating holes for the mechanism and screws.
- Drill bits: Specifically, 2mm, 5mm, 8mm, and 16mm drill bits are required.
- Crosshead screwdriver: For driving crosshead screws.
- Flathead screwdriver: For driving flathead screws.
- Chisel: For creating recesses for the lock body and strike plate.
Diagrams on page 2 show these tools.
Installation Steps
Step 1: Mark the Door
Mark the desired location for the lock mechanism and associated holes on the door. Refer to the front plate template on page 7. For Euro cylinder locks, use Template A (page 8). For thumbturn locks, use Template B (page 9).
Note: Ensure you only mark the holes relevant to your specific hardware; not all marked holes may be necessary.
Diagram on page 3 illustrates marking the door.
Step 2: Orient the Latch
Verify that the lock latch is correctly oriented. If it is not, turn the lock body upside down. Release the limiter tab, push the latch fully down, and rotate it into the correct position within the available gap.
Diagram on page 3 shows latch orientation.
Step 3: Drill the Mechanism Pocket
Using a 16mm drill bit, drill out the pocket on the door edge to house the lock mechanism. Consult page 7 for a template to guide this process. The pocket depth is typically 165mm.
Diagrams on page 3 show drilling with a 16mm bit and the required depth.
Step 4: Chisel Pocket Edges
Use a chisel to carefully shape and square the edges of the drilled pocket on the door.
Diagram on page 3 illustrates chiseling.
Step 5: Position and Mark Front Plate
Insert the lock body into the prepared pocket. Position the front plate and carefully mark its outline onto the door. For precise results, it is recommended to score the outline with a sharp blade.
Diagrams on page 4 show inserting the lock and marking the plate outline.
Step 6: Chisel Front Plate Recess
Chisel out a recess approximately 3mm deep on the door surface to accommodate the front plate, ensuring it sits flush.
Diagram on page 4 shows chiseling the recess.
Step 7: Drill Spindle and Lock Holes
Drill the necessary holes for the spindle and the lock mechanism as marked. It is advisable to drill from both sides of the door to ensure the holes are straight and to minimize the risk of the door splintering.
Diagram on page 4 illustrates drilling these holes.
Step 8: Test Fit the Lock
Insert the lock body again to confirm that it fits correctly and that all drilled holes align properly with the lock's components.
Diagram on page 4 shows testing the fit.
Step 9: Mark and Drill Pilot Holes (Outer Screws)
Using the lock body as a guide, mark and drill 2mm pilot holes for the outer screws that will secure the lock.
Diagram on page 4 illustrates marking and drilling pilot holes.
Step 10: Mark and Drill Pilot Holes (Inner Screws)
Mark and drill 5mm holes, approximately 4mm deep, for the inner screws that attach the lock body.
Diagram on page 4 illustrates marking and drilling these shallow holes.
Step 11: Secure the Lock Body
Use the supplied crosshead wood screws to firmly fix the lock body into the door.
Diagram on page 5 shows screws being used.
Step 12: Attach the Front Plate
Use the flathead facing screws to attach the front plate to the lock body, completing the installation of the lock mechanism.
Diagram on page 5 shows attaching the front plate.
Step 13: Mark the Strike Plate
Position the strike plate on the door frame. The top edge of the strike plate should be level with the top edge of the lock's front plate. Mark the outline of the strike plate on the door frame.
Diagram on page 5 illustrates marking the strike plate.
Step 14: Drill Strike Plate Hole
Drill out the main opening for the strike plate in the door frame.
Diagram on page 5 shows drilling the strike plate hole.
Step 15: Square the Strike Plate Hole
Use a chisel to remove any remaining material and ensure the hole for the strike plate is square and clean.
Diagram on page 6 illustrates chiseling.
Step 16: Chisel Strike Plate Recess
Chisel out a recess in the door frame to allow the strike plate to sit flush with the frame surface.
Diagram on page 6 illustrates chiseling the recess.
Step 17: Mark and Drill Strike Plate Pilot Holes
Mark the positions for the strike plate screws and drill pilot holes into the door frame.
Diagram on page 6 illustrates marking and drilling pilot holes.
Step 18: Secure the Strike Plate
Screw the strike plate securely to the door frame using the supplied flathead wood screws.
Diagram on page 6 shows screwing the strike plate.
