Tools and Materials for Installing Extendable Window Bars

Extendable Window Bars are one of the simplest and most effective ways to improve window security. This guide explains the basic installation process for DIY Xpanda Window Bars using common household tools.

Step 1: Measure Inside Your Window Frame

Begin by measuring the inside width and height of your window frame.

Particularly inside the window frame's reveal.

These measurements will help determine:

• The correct window bar size
• Whether the bars should be installed horizontally or vertically
• Whether multiple bars are required for larger openings

Take your time during this step, as accurate measurements are essential for a secure installation.

Important: To maintain strength and rigidity, avoid selecting a bar that is expanded to its absolute maximum width or height.

For example, if your window opening is 900mm wide, avoid choosing a bar with a maximum width of 900mm. Instead, choose a larger size such as 1100mm or 1650mm and install it partially expanded for improved strength.

Round Bars vs Square Bars

Round Window Bars are designed for installation inside the reveal (sill-fix).

Square Window Bars can be installed inside the reveal or mounted over the face of the frame (face-fix), providing additional installation flexibility.

Step 2: Gather Your Tools and Materials

Before beginning, make sure you have the following:

• DIY Xpanda Window Bars
• Measuring tape
• Pencil or marker
• Drill and suitable drill bits
• Screws and fixings (included)
• Screwdriver
• Spirit level

Step 3: Mark the Mounting Points

Position the bars where they will be installed and mark the locations for the mounting brackets.

Use a spirit level to ensure the bars will be straight and evenly aligned. Double-check all measurements before drilling.

Step 4: Drill the Holes

Drill holes at the marked locations.

If installing into brick, concrete, or masonry surfaces, use the appropriate drill bit and wall anchors.

Taking a little extra time here will help ensure a secure and professional-looking installation.

Step 5: Attach the Mounting Brackets

Secure the mounting brackets using the supplied screws and fixings.

Ensure all brackets are firmly attached and properly aligned, as they provide the foundation for the installation.

Step 6: Install the Window Bars

Expand the window bars to suit the opening and position them within the mounting brackets.

Check that the bars are level and centred before tightening all adjustment screws and fixings.

Step 7: Test the Installation

Apply gentle pressure to the bars to confirm they are firmly secured.

The bars should feel stable with minimal movement. If necessary, tighten the mounting brackets or adjustment screws and make any final alignment adjustments.

Before finishing:

• Check all screws and fixings are tight
• Confirm the bars are level
• Remove any installation debris
• Verify the installation is secure

Your window bars are now ready to provide a strong visual deterrent and an additional layer of protection for your home, rental property, garage, or other vulnerable openings.
