Door Lining Jig

About the Door Lining Jig

The door lining jig from Reptile Jigs is a revolutionary tool that enables carpenters to efficiently and accurately fit door linings with precise margins around the door. With this jig, carpenters can complete door lining installations in under 10 minutes, saving valuable time and effort.

Key Features and Benefits

• Precision Fit: The door lining jig allows for precise margins around the door, eliminating the need for wedges or shims. This ensures a professional finish every time.
• Easy Installation: The jig features rotatable arms on the top, allowing the user to position the frame according to the door's dimensions. It also has a built-in spirit level for easy adjustment.
• Multiple Door Sizes: The lining jig can accommodate a range of door sizes, including 526mm, 533mm, 610mm, 626mm, 686mm, 711mm, 726mm, 762mm, 813mm, 826mm, 838mm, 864mm, 915mm, and 926mm.
• Flexible Margins: With three margin settings of 2mm, 3mm, and 4mm, the jig allows for precise gaps around the door, suitable for both standard doors and fire doors.
• Sturdy Construction: The jig is made from durable materials and features multiple holes around the frame for screwing the frame to the door lining. It also includes slightly larger holes for visual confirmation of proper contact between the door lining and the frame.
• Quick Assembly: The lining jig frame can be easily assembled in less than one minute and disassembled just as quickly, making it highly convenient for carpenters on the job.
• Compact Design: When disassembled, the jig has a small footprint of 1200mm in height and 600mm in width, shaped like the letter L. This allows for easy storage and transportation.
• Pre-Drilled Holes: To ensure a secure fit, it is recommended to pre-drill holes approximately 10mm deep on the door lining for the screws.

How to Use the Door Lining Jig

Using the door lining jig is a straightforward process. Follow these steps for successful door lining installations:

1. Prepare the door frame: Ensure the door frame is properly aligned and securely fixed in place.
2. Set the margin: Select the desired margin setting (2mm, 3mm, or 4mm) on the door lining jig.
3. Position the jig: Place the jig around the door frame, aligning it with the margins you want to achieve.
4. Secure the jig: Use screws to fix the jig to the door frame, ensuring a stable and secure setup.
5. Pre-drill holes: On the door lining, pre-drill holes approximately 10mm deep using a drill bit slightly larger than the screws.
6. Install the door lining: Fit the door lining within the jig, aligning it with the door frame and desired margins.
7. Secure the door lining: Insert screws into the pre-drilled holes on the door lining and screw them in until they bury beneath the recessed holes. Be careful not to overtighten and pull the lining; the goal is to hide the screw heads in the holes while maintaining a secure fit.
8. Repeat the process: Depending on the width of the MDF lining, you may need to use five pairs of screws on each side and a pair in the header. However, for shallow-width MDF linings, you may get away with using only five screws per side without pairs.
9. Follow the proper screwing order: Refer to the instructions in the YouTube video for the specific order in which to screw the linings to the studwork.
10. Remove the jig: Once the door lining is securely in place, carefully remove the jig.
11. Check alignment: Inspect the installation to ensure the door lining is properly aligned and the margins are consistent.

Common Mistakes and Tips

• Ensure the door lining jig is properly assembled and secure before use.
• Double-check the door size and select the appropriate margin setting for the desired gap.
• Use 80mm fully threaded screws for optimal strength and stability.
• Verify that the door lining is in proper contact with the frame by visually checking the larger holes provided.
• Take advantage of the rotatable arms and built-in spirit level to achieve precise positioning and alignment.
• Always follow safety precautions and use appropriate personal protective equipment (PPE) during installation.
