Need a fully vented window for your older domestic curved-body van?

The CRL Universal Vented Van Window (FW904RS) features a contoured design ideal for various positions on US domestic vans like Ford, Chevy, and GMC models with pronounced curves. It offers a sleek appearance with dark privacy glass and a black powder-coated interior frame, hidden from outside view by the silkscreened black fade edge (frit) on the glass.

This window is a universal fit, so you’ll need to verify that its dimensions and contour align with your van’s exterior curvature and interior structural ribs before installation.

IMPORTANT: The FW904RS is designed specifically for highly curved van bodies typical of older domestic GMC, Ford, and Chevy vans. For 2007+ Sprinter, Transit, or Promaster vans with a less curved van body, check out the FW632RS window.

NO SHIPPING CHARGES if you pick up your van window at any of the 18 CRL warehouses in the US

Install Info

Notes when mounting your clamp-in van window:

Clamp-in windows can not replace factory glass windows due to the oversized cut-out.
MUST cut window hole to fit clamp ring specifications.
Cut the openings with a center-blade shear, rather than a jigsaw - this will cut an opening that may be less ragged, produce less debris, and produce less hammering on the sheet metal of the van.
Make sure you paint the cut edges of the new window opening - if you skip this step, moisture can rust out the edges of the window mounting.
IMPORTANT: these windows clamp-in place - we recommend you use hand tools to tighten these. DO NOT use power tools on the inner trim ring screws.
See our AW3310 clamp-in install guide for more details.

FAQ

Q1: What is a clamp-in window?

A: A clamp-in window uses an interior clamp ring and exterior frame to secure the window to the van wall—no adhesive or primer required. It’s a popular choice for DIY installs because it’s easier and faster to install than bond-in windows.

Q2: Are clamp-in windows compatible with my van?

A: Yes! Clamp-in windows are available for most popular vans including Ford Transit, RAM ProMaster, and Mercedes Sprinter. Always check product specs to confirm fitment for your specific roof height, wheelbase, and model year.

Q3: What’s the difference between clamp-in and bond-in windows?

A: Clamp-in windows use a mechanical frame and clamp ring to secure the window—no adhesive needed.

Bond-in windows use urethane adhesive for a flush, frameless look. Clamp-in windows are easier to install but may not be as low-profile as bond-in styles.

Q4: Can I install a clamp-in window myself?

A: Yes! Clamp-in windows are ideal for DIY van builders. They don’t require adhesive or curing time and include all hardware for a secure fit. Just be sure to measure carefully and follow cutting instructions closely.

Q5: What tools do I need to install a clamp-in window?

A: Basic tools include:

Jigsaw or body saw with metal blades
Masking tape and marker for layout
File or deburring tool for smoothing edges
Screwdriver for securing clamp ring attachment
No special adhesives or primers are required.

Q6: Is any adhesive or sealant required?

A: Typically, clamp-in windows come with a rubber gasket or foam seal to prevent leaks. You may use a small amount of butyl tape or RV sealant around the frame for extra water resistance, but it’s not always necessary.

Q7: Are clamp-in windows watertight and secure?

A: Yes—when properly installed, clamp-in windows are watertight, wind-resistant, and secure for all weather conditions. Always double-check the gasket alignment during install to ensure a tight seal.

Q8: Can clamp-in windows open for ventilation?

A: Many clamp-in windows include sliding or crank-out panels with built-in bug screens. Others are fixed-pane solid glass. Be sure to check if the model you’re selecting includes ventilation features.

Q9: Can clamp-in windows be installed in vans with no factory windows?

A: Absolutely. Clamp-in windows are designed for cargo vans with solid panels and can be installed after carefully cutting the correct window openings using the included template or manufacturer’s specs.

Q10: Do clamp-in windows meet safety standards?

A: Yes. Most clamp-in windows are made from tempered safety glass and meet applicable safety standards like DOT FMVSS 205 and ANSI Z26.1 for automotive windows.
