3.2. Setup and Adjustment
- Prepare the Door: Ensure the door surface is clean and free of obstructions. If installing on a new door slab, ensure it is properly sized and positioned.
- Attach the Template: Position the hinge router template on the edge of the door where the hinge mortise is required. The built-in plastic clamp attaches to standard door thicknesses. Tighten the clamp securely to prevent any movement.
- Adjust Hinge Length: Use the integrated adjustment tool to set the template for the desired hinge length (e.g., 3 in., 3.5 in., 4 in., 5 in.).
- Set Router Bit Depth: Insert the Carbide Hinge Tip Router Cutter into your router. Use the template's built-in tip depth gauge to set the correct routing depth for your hinge thickness.
- Select Corner Type: The template supports both square and rounded hinge corners. Ensure your router bit matches the desired corner type.
- Optional: Removable Front Guide: For compact chisels or routers, the removable front guide can be used for additional support.
3.3. Operation: Creating Hinge Mortises
- Secure the Router: Ensure your router is securely fitted with the correct bit and depth setting.
- Route the Mortise: Carefully guide the router along the inner edges of the template. Maintain steady pressure and a consistent speed to create a clean, even mortise.
- Clean the Mortise: After routing, remove any wood chips or debris. If using square hinges, use a chisel to square off the corners if the router bit created rounded corners.
- Repeat for Additional Hinges: Reposition the template for each subsequent hinge location, ensuring consistent spacing and alignment.
4. RYOBI A99DLK4 Wood/Metal Door Lock Installation Kit

4.2. Setup and Adjustment
- Prepare the Door: Ensure the door is securely positioned. The template fits standard-sized wooden or light metal doors.
- Position the Jig: Place the lock installation jig on the edge of the door. The auto-strike locator helps align the jig with the existing strike plate or desired latch position.
- Secure the Jig: Push the 'S' into the latch bore area to help stabilize the jig. For additional stability, ensure the jig is held firmly against the door.
- Set Backset: Use the built-in adjuster to set the desired backset measurement (distance from the edge of the door to the center of the main hole). Common backsets are 2-3/8" or 2-3/4".
4.3. Operation: Drilling Lock and Latch Bores
- Drill the Cross Bore (Main Lock Hole):
- Attach the shaft and pilot drill to the 2-1/8" hole saw.
- Insert the hole saw assembly into your drill.
- Align the pilot drill with the center guide of the jig for the main lock hole.
- Drill through the door, maintaining a steady and controlled motion, until the hole is complete.
- Drill the Latch Bore:
- Remove the 2-1/8" hole saw.
- Attach the 1" hole saw or the wood drill bit to your drill.
- Align the bit with the latch bore guide on the edge of the jig.
- Drill into the door edge until the latch bore is complete and connects with the cross bore.
- Install Hardware: Once both holes are drilled, remove the jig and proceed with installing your lock and latch hardware according to their specific instructions.
5. Maintenance
Proper maintenance ensures the longevity and performance of your RYOBI installation kits.
- Cleaning: After each use, clean the templates and bits to remove wood dust, debris, or metal shavings. Use a dry cloth or soft brush. Do not use harsh chemicals that may damage the plastic.
- Bit Care: Inspect router bits and hole saws for wear or damage. Replace dull or damaged bits to ensure clean cuts and prevent strain on your power tools.
- Storage: Store the kits in a dry, clean place, away from direct sunlight and extreme temperatures. Keep all components together to prevent loss.
