Introduction
Adding a CR Laurence T-Vent window to a van—particularly a Sprinter or cargo van—can significantly enhance the living experience by introducing natural light and ventilation. These windows are designed to provide a balance between functionality and aesthetics, with features such as awning-style venting, double-pane construction, and integrated trim systems. The installation process, however, requires careful preparation, patience, and attention to detail to ensure a secure and long-lasting fit.
The information presented here is derived from firsthand accounts, technical tips, and product-specific guidance from multiple sources, including installation logs, product descriptions, and user experiences. This guide compiles the most relevant and verified steps from those sources to offer a comprehensive, step-by-step approach to installing CR Laurence T-Vent windows in Sprinter and cargo vans.
Choosing the Right Window for Your Van
Before beginning the installation process, it is essential to choose the appropriate CR Laurence window model for your vehicle. The documentation specifies several models tailored to different van configurations. For example, the 2007-current Sprinter vans are compatible with the following options:
- Driver Side Forward T-Vent Window (144 or 170)
- Passenger Side Sliding Door T-Vent Window (144 or 170)
- 170-Only Driver Side Fixed Middle Window
- 170-Only Passenger Side Fixed Middle Window
- 170-Only Driver Side Rear T-Vent Window
- 170-Only Passenger Side Rear T-Vent Window
- 144-Only Driver Side Rear T-Vent Window
- 144-Only Passenger Side Fixed Window (T-Vent not available for 144 passenger side rear due to sliding door conflict)
For other platforms, such as the Ram ProMaster and Ford Transit, similar model-specific compatibility applies. It is recommended to verify the correct model for your van configuration before cutting into the body.
Additionally, users have noted that CR Laurence and AM Auto windows are cut-to-fit, meaning they can be adapted to the specific dimensions of the van. In contrast, Arctic Tern windows are pre-cut and may not conform to the body lines of the vehicle. The CR Laurence and AM Auto models are generally preferred for custom van builds due to their flexibility in installation and integration with the vehicle's structure.
Preparing for Installation
Unboxing and Inspection
Before cutting into the van, it is crucial to unbox the window and inspect it for any damage or missing components. Ensure that all mounting parts—such as the clamp ring and installation screws—are present and in good condition. A recommended practice is to test the clamp ring against the vehicle's contour to confirm it matches the expected shape of the cutout.
Tools and Safety Precautions
The installation process involves cutting into the van's body, which requires a set of specialized tools and a strong focus on safety. The following tools are commonly recommended:
- A saw suitable for cutting aluminum or metal (e.g., a jigsaw or reciprocating saw)
- A drill and appropriate drill bits
- A deburring tool or file
- A paintbrush for applying protective paint
- A screwdriver (Phillips head is typically used)
- Clamps and a helper to assist with holding the window in place during installation
Safety equipment such as gloves, safety glasses, and a dust mask should also be worn to protect against metal shavings and debris.
Marking and Cutting the Opening
Before making any cuts, the window must be placed against the van to determine the precise location and size of the opening. Mark the cut lines carefully, and double-check the alignment to ensure the window will fit snugly after installation.
Once the marks are made, use a saw to cut along the lines. It is important to maintain a steady hand and follow the marked lines closely to avoid misalignment. After cutting, use a deburring tool to smooth the edges and remove any sharp or rough surfaces.
Preventing Corrosion and Contamination
During the cutting process, metal shavings (referred to as "swarf") can fall into the wall cavities and lead to rust formation over time. To prevent this, users recommend using blue painter’s tape and plastic drop cloths to contain the debris. This step is especially important for Sprinter vans, which have built-in templates that can help guide the cutting process.
After deburring, apply a coat of paint to the exposed metal surfaces. This not only enhances the aesthetic appearance but also provides a protective barrier against corrosion.
Step-by-Step Installation Process
Test Fitting the Window
Before proceeding with the final installation, place the window into the cutout to test the fit. If the window does not fit cleanly, check the corners for any misalignment and make necessary adjustments. Reapply paint to the modified areas to protect the metal.
Once the window is properly aligned, have one person hold it in place from the outside while another works from the inside.
Installing the Clamp Ring
With the window in position, fit the clamp ring around the window from the inside. Ensure the ring is aligned with the cutout and install all the screws, but do not tighten them at this stage. This allows for final adjustments to the window's position. Once the alignment is confirmed, tighten the screws gradually in a circular motion to ensure even pressure is applied.
The clamp ring should be installed with the split in the flange pointing downward. One recommended method is to start by tightening a screw at the split and then working around the ring in either a clockwise or counter-clockwise direction. This approach helps minimize gaps at the split and ensures a tight fit.
Installing the Glass
With the clamp ring in place, the glass can be installed. It is advisable to have a helper assist with this step. Before placing the glass, spray water on both the perimeter of the cutout and the gasket to reduce friction and ensure a smooth seating of the gasket against the van.
Have the helper lift the window into place and apply gentle pressure to hold it. From the inside, use a Phillips head screwdriver to begin securing the glass in place.
Fitting the Trim Ring
Once the window is secured, the trim ring can be installed. Fit the trim ring around the window, ensuring the split in the flange is oriented downward. Begin tightening the screws at the split and work your way around the ring in a circular pattern. This method helps achieve a tighter fit and minimizes gaps at the split.
Some users report that starting with a single screw at the split and tightening gradually provides the best results. Repeating this process for the remaining screws ensures even pressure and a secure fit.
Post-Installation Considerations
Ventilation and Aesthetics
CR Laurence T-Vent windows offer awning-style ventilation, allowing the glass to rotate upward and outward. This feature is particularly beneficial for maintaining airflow even in rainy conditions. Users have noted that the placement of windows can significantly affect the overall comfort and functionality of the van, especially in areas such as sleeping quarters or workspaces.
In addition to ventilation, the windows contribute to the aesthetic appeal of the van by bringing in natural light. This can make a confined space feel more open and inviting, enhancing the overall living experience.
Maintenance and Longevity
To maintain the performance and appearance of the window, regular cleaning and inspection are recommended. The gasket should be checked for wear or damage, and any signs of corrosion should be addressed promptly. Applying a fresh coat of paint to exposed metal surfaces can also help extend the lifespan of the installation.
Users who have installed these windows since as early as 2016 report no significant issues, indicating that with proper installation and care, the windows can provide long-term functionality.
Conclusion
CR Laurence T-Vent windows offer a versatile and durable solution for adding ventilation and natural light to Sprinter and cargo vans. The installation process, while requiring precision and care, is manageable with the right tools and preparation. By following the outlined steps—including selecting the appropriate model, preparing the installation area, test-fitting the window, and securing the clamp and trim rings—users can achieve a professional-looking result that enhances both the aesthetics and functionality of their van.
Careful attention to detail during each step, particularly in preventing corrosion and ensuring proper alignment, is essential for a successful installation. With the right approach, CR Laurence windows can provide years of reliable service, contributing to a more comfortable and enjoyable van living experience.
