At Upfit Supply, we’re always looking for smart, functional upgrades that add value and comfort to your commercial vehicle setup. Today, we’re diving into the Unboxing of the Weather Guard Composite Partition Window Kit—a practical accessory that brings visibility and added safety to your CabMax composite bulkhead system.

If you’re running a full-size van like the GMC Savana, Chevy Express, Ford Transit, RAM ProMaster, or Mercedes Sprinter, and you’ve already installed a Weather Guard composite partition, this kit might be the perfect add-on. Let’s walk through what comes in the box, how it works, and why it’s a game-changer for fleet visibility and function.

What Comes in the Box?

First up, let’s break down what you’ll find when you open the Weather Guard Composite Partition Window Kit:

  • Crystal-clear plexiglass panel with protective film
  • Two metal window mounting brackets
  • Complete hardware set, including Philips head bolts, washers, and lock nuts
  • Full-color printed installation guide (no QR code chase required)

Every component is packed securely, and the included manual gives you clear, step-by-step instructions.

Designed for Full-Size Vans Only

It’s important to note that this partition window kit is only compatible with Weather Guard CabMax composite partitions installed in full-size vans. Supported vehicle models include:

  • Ford Transit (various roof heights)
  • RAM ProMaster
  • Chevrolet Express / GMC Savana
  • Mercedes-Benz Sprinter

Keep in mind that installation depends on having the composite partition already in place. If you’re looking to add this kit to your setup, make sure you’ve got the correct base partition first.

Quick Look at the Features

This isn’t just a window—it’s a well-thought-out accessory that brings multiple benefits. Here’s what stands out:

  • Crystal-clear visibility from the cab to the rear cargo area
  • Retains use of your factory rear windows
  • Tough, lightweight plexiglass that resists cracking and shattering
  • Brackets provide secure mounting to avoid rattle or flex during driving
  • Protective film ensures the lens arrives scratch-free
  • Easy-to-install hardware—just a few bolts and you’re done
  • Professional finish that integrates seamlessly with the composite bulkhead

Installing the Partition Window Kit

This kit is engineered for easy installation, whether you’re a DIY upfitter or a professional installer. With basic hand tools, you’ll be up and running in under an hour.

Installation Overview:

  1. Remove the protective film from the plexiglass panel
  2. Position the brackets on either side of the plexiglass to form a secure “sandwich”
  3. Place the assembly into the designated opening on the composite partition
  4. Use the included bolts and lock nuts to secure everything in place
  5. Double-check for tightness and ensure the window sits flush

This simple process requires no advanced tools or fabrication work.

Why Add a Window to Your Partition?

Visibility is often overlooked when upfitting a van, but it plays a crucial role in safety and efficiency. Here’s why this Weather Guard window kit is worth considering:

  • Enhanced safety: See what’s happening behind you before making decisions
  • Better use of rear windows: Maintain rear visibility if your van has rear glass
  • Ideal for delivery or utility work where rear monitoring is helpful
  • Cleaner look than aftermarket cutouts or DIY panels
  • Adds resale value to your vehicle with a professional, factory-like install

A Closer Look at the Materials

The plexiglass panel is sturdy, shatter-resistant, and lightweight. It’s designed to handle temperature changes without warping. The mounting brackets are rigid and powder-coated for durability.

Because this product is made specifically for Weather Guard CabMax composite partitions, you’re guaranteed a precise fit with no need for cutting, grinding, or adjusting.
