Most window shades ask something of the wall. They require brackets, screws, a small commitment to permanence. Once installed, they leave a trace behind, even when the shade itself is removed.

The TrueFit Bar™ takes a different approach. It holds itself in place using pressure, expanding to meet the width of your window frame and settling into position through tension. Nothing is drilled, and nothing is fixed in a way that cannot be undone. The installation relies on balance rather than force, which can feel unfamiliar at first, especially if you are used to drilling holes.

That instinct is understandable. It is also not necessary here.

The bar expands inside the window frame and is then tightened just enough to hold its position. What you are doing during installation is not forcing the bar into place, but guiding it there. You extend it to the correct width, position it so it sits evenly within the frame, and tighten it until it feels stable.

It is normal for the bar to shift slightly as you adjust it. That movement is part of the process, not a sign that something is wrong. You are looking for a point where both sides feel evenly supported, where the bar settles into place rather than needing to be pushed or tightened further.

This is a system that depends on alignment as much as pressure.

A correct installation does not feel rigid in the way a bracket might. Instead, it feels stable when you press on it, evenly supported from side to side, and slightly responsive when tapped. There may be a small amount of movement in the middle of the rod, which can feel counterintuitive at first, but is simply a result of how the system distributes tension across the frame.

If the bar stays in position when pressed and does not shift when you tap on it, it is installed correctly. At that point, adding more tension does not improve the installation.

In the vast majority of windows, the TrueFit Bar works on its own. Once installed correctly, it holds its position through tension and does not require additional support, which is why most installations stop there.

There are situations, however, where the surface of the window frame or the shape of the opening makes that balance harder to achieve. The bar may feel slightly unsettled, or you may simply prefer something that feels more fixed, less dependent on the subtle equilibrium of pressure and alignment.

For those cases, TrueFit Anchors are included.

They change the nature of the installation slightly, giving the ends of the bar a defined place to sit and turning something that floats into something that rests.

TrueFit Anchors attach to the window frame and act as a resting point for the ends of the bar. They can be installed in two ways, depending on how permanent you want the result to be.

Using adhesive dots allows you to place the mounts without drilling, adding stability while keeping the installation simple and reversible. Using screws fixes the mounts directly to the frame, creating a more permanent solution that removes any remaining movement.

In both cases, the outcome is the same. The ends of the TrueFit Bar sit inside the mounts and are tightened in place, reducing variation and making the position of the bar more defined.

It helps to think of the system as a progression rather than a set of decisions you need to make all at once. You begin with the TrueFit Bar on its own, which is sufficient in most cases. If the installation does not feel as stable as you would like, you can introduce the mounts using the adhesive option, and if you prefer something more permanent, you can move to screws.

Most people stop at the first step.

The additional parts are there to meet the edge cases, not to complicate the default experience.

Once installed, the TrueFit Bar becomes the foundation for everything that follows. When it is balanced and properly supported, the shade moves smoothly and predictably, and the installation holds its position over time without requiring constant adjustment.

The goal is not to make the system immovable, but to create something that sits comfortably within the space, held in place by the shape of the window itself. It is a different way of thinking about installation, one that becomes less noticeable once it is in place.

And then, it simply works.
