DIY Xpanda's extendable window bars are often chosen by window repair agents, property management/maintenance companies, security professionals, and many other individual businesses/ homeowners, due to their flexibility in sizes and high resiliency in many different applications.

These window bars offer an affordable and reliable DIY home security solution to achieve burglar-proof home and business. These window bars can secure windows from the inside, especially useful in high-crime areas or when the property will be unoccupied for an extended period, suitable for securing ground-level and basement windows and vulnerable upper-level windows at residential and commercial properties.

Our extendable window bars can also be used in conjunction with other security measures such as alarm systems, motion detectors, and security camera to secure your windows and families.

How to install Extendable Window Bars

Step 1: Measure Inside Your Window Frame

First things first, let's measure the inside of your window frame.

Particularly inside the window frame's reveal. 

This step is important because it will help you decide whether to install the bars vertically, horizontally, or even use multiple bars side-by-side. Take your time with this part—no need to rush. Think about which windows or doors you want to secure the most to protect your home.

Also, to retain rigidity in the middle of the bars, do not exceed the maximum expanded width/height.
So if you have a window size that is 900mm width by 900 mm width, you would not want to choose the window bar that extends to 900 or 905mm, rather choose that extends to something like 1100mm or 1650mm.

<Round or Square Bars>

One thing to note, if you are choosing square bars, you can install the expanding window security bars on top of the frame / reveal in addition to installing them inside the frame (window sill)

Step 2: Gather Your Tools and Materials

Before we get started, let's make sure we have everything we need.
Here’s a list of tools and materials:

• DIY Xpanda expandable window security bars
• Measuring tape
• Pencil or marker
• Drill with the right drill bits
• Screws and anchors (included in the expandable window security bars)
• Screwdriver
• Level

 

Step 3: Mark the Mounting Points

Using your measurements from Step 1, mark the spots on the window frame where you’ll drill the holes for the mounting brackets. Make sure the marks are level and evenly spaced. Double-checking your marks now will save you from any hassles later on.

Step 4: Drill the Holes

Now, it’s time to drill the holes. Be gentle and precise, using the marks as your guide. If you’re drilling into a tougher surface like masonry or concrete, use the appropriate drill bit and anchors. Take it slow and steady.

Step 5: Attach the Mounting Brackets

Next, attach the mounting brackets to the window frame with the screws and anchors. Make sure they’re nice and tight. The brackets need to be stable to keep the expandable window bars secure.

Step 6: Install the Expandable Window Security Bars

Expand the window security bars to fit the width of your window frame. Place them into the mounting brackets and make sure they’re aligned properly. Tighten any adjustment screws or bolts to lock the bars in place.

Step 7: Test the Security

Give the expandable window security bars a gentle push and pull to check their stability. They should be firmly in place without any wobbling. If they feel loose, tighten the brackets or adjustment screws a bit more. 
Make any last adjustments to ensure everything is just right.
Check all screws and brackets to make sure they’re tight, and clean up any debris from the installation.
