If you’ve ever tried to replace a window or sliding door part, you already know the struggle:

“What brand is this?”
“What model do I even have?”
“How do I know which part to order?”

You’re not alone.

One of the easiest and most overlooked ways to identify your window or door hardware is by checking decals, those small stickers or labels tucked away on the frame. These tiny clues contain valuable information that can save you hours of guesswork, back-and-forth messages, and incorrect orders.

In this guide, we’ll walk you through where to find decals, what they mean, and how they help you identify the correct parts quickly and accurately.

If you’re more of a visual learner, here’s a quick video that walks you through exactly where decals are located and how to use them to identify the correct parts:

📹 How to Identify Parts Using Decals

What Are Decals and Why Do They Matter?

Decals (or product labels) are small stickers placed by manufacturers or installers. They often include:
✔ Brand or manufacturer
✔ Product series or model
✔ Compliance information
✔ Safety details
✔ Sometimes even part numbers

These details are incredibly useful when you’re trying to match or replace components, especially if the window or sliding door is older, discontinued, or has been through multiple renovations over the years.

Where to Find Decals on Your Windows and Doors

Decals can be located in different areas depending on the brand and age of the system. Common locations include:

🔍 Sliding Doors

• Inside the frame near the latch
• Along the fixed panel
• On the vertical stile of the moving panel
• Behind or near the handle

🔍 Windows (Awning, Casement, Sliding, Double-Hung)

• Inside the top or bottom track
• On the jamb (vertical frame)
• Behind the flyscreen
• On the inside face of the sash

If you’re not sure, take your time and look closely, some decals fade or hide under years of paint or dust.

Understanding What the Decal Tells You

Different manufacturers include different information, but many decals will include key identifiers like:

Brand Name

This is the biggest clue. For example, if the decal shows:

• ALSPEC
• WINTEC
• VANTAGE
• DOWELL
• STEGBAR

You’re already halfway to finding the correct hardware.

Series or System Name

E.g., “Viewmax”, “Commercial Sliding Door Series”, “Wintec 100 Range”
This helps narrow down compatible rollers, handles, locks, and guides.

Compliance/Safety Info

This is highly useful for identifying sliding door safety decals, especially for glass compliance.

How Decals Help You Identify the Right Replacement Parts

Once you know the brand and series, you can:

✔ Identify compatible rollers
✔ Match the correct handle type
✔ Find the right wheel profile
✔ Determine which keeper or strike fits
✔ Avoid buying parts that look similar but won’t fit your system

This saves you money, reduces stress, and ensures smoother sliding or locking action once the new part is installed.

What If Your Decal Is Missing or Faded?

It happens, especially on older aluminium windows.
Don't worry; you still have options.

You can identify parts using:

• Measurements
• Wheel type and diameter
• Handle shape
• Track profile
• Locking mechanism style

Tips for Taking Photos for Correct Identification

If you need help identifying parts, send us photos showing:

1. The full window/door
2. Close-ups of the rollers or handles
3. Measurements where possible
4. Any remaining decals or stamped logos

Clear photos = quick and accurate support.
