Choosing the Best Types of Window Cranks

| August 18, 2024

Are you on the hunt for a suitable window crank handle? Excellent, ’cause we’ve got the perfect guide!

While it may seem like an insignificant window part, the crank handle can enhance or detract from your windows’ efficiency and style. That’s why looking through different types of window cranks and picking one that suits your windows best is definitely worth your time!

This article simplifies the choice, presenting all the options for your casement or awning windows – from the elegance of classic designs to the simplicity of modern mechanisms!

Key Takeaways

  • There are several types of crank handles on the market, including fixed cranks, fold-down and fold-away cranks, and T cranks. There are also crank handles that have a screw and handles that can be simply pushed onto the spline.
  • Choosing the correct type of crank is essential for casement and awning windows, as it affects the window’s operation, energy efficiency, and ease of use.
  • If you need to replace the whole crank mechanism, you’ll have to buy a crank set, which includes a window operator that has to match the existing one.
  • If you’re tired of replacing crank mechanisms, install Magic crankless windows featuring our award-winning Parallex Hardware system.

Understanding Window Crank Types

Generally, there are four types of crank handles:

  • Fixed handles, which are – well, obviously – fixed
  • Fold-downhandles, which fold down into the sill
  • Fold-away handles, which fold back into themselves
  • Tee (T) cranks or butterfly handles

Furthermore, crank handles can be distinguished based on how they’re installed:

  • Snap-onhandles, which have no screws; to find a suitable replacement for a snap-on crank handle, use a screwdriver to remove it gently from the spline; measure the base of the spline and count how many protrusions (teeth) it has.
  • Set screw handles, which have a screw; to find a suitable replacement for a set screw crank handle, you’ll have to loosen the screw to remove the handle and then follow the same steps as with snap-on handles.

It’s not mandatory to replace a crank handle with a new one that’s installed the same way. For example, you can easily replace a set screw handle with a snap-on handle.

Crank Handle Designs

The next step is picking a crank handle design! With an array of styles that cater to both the timeless charm and the contemporary chic, the right window crank can undoubtedly complement your home’s unique character!

Classic Crank Handles

Classic crank handles:

  • Echo the craftsmanship of the past
  • Bring an air of tradition to your casement windows
  • Are constructed from durable materials like brass and metal

Whether you prefer the rustic charm of bronze or the polished sophistication of steel, these handles add an ornamental touch that is at once timeless and dignified.

Modern Styles

Modern window cranks embrace minimalist lines and are crafted from materials praised for their stylish appeal. One of the most sought-after for contemporary and elegant designs is the Tee (T) casement window crank handle, which ensures easy operation and serves as a subtle yet unique window part.

Other designs combine style and performance for a modern space – for example, some Truth Hardware casement window handles and covers feature a concealed magnet that draws the handle into place.

Sleek Folding Options

For those with an eye for efficiency and a desire for uncluttered spaces, a sleek folding crank handle is a solution that’s as smart as it is stylish. It folds down towards the window sill when not in use, ensuring that your window treatments and views remain undisturbed.

These folding casement window hardware options are perfect for windows that feature treatments like roller shades or blinds. A folding crank handle will be perfectly hidden, so it won’t be noticeable behind the shades.

Material Matters: Selecting Durable Window Cranks

Obviously, the design isn’t the only thing that matters in the process of choosing a good crank for awning or casement windows. One of the most important features to consider is the material – you definitely want a durable one; otherwise, you’ll spend too much time and money on repeatedly replacing cranks that show signs of wear and tear. Crank handles are usually made of metal or plastic, so it’s basically a decision between durability and cost-efficiency.

Metal cranks boast superior durability and resistance to discoloration, but they come at a higher cost. On the other hand, plastic cranks, while less durable, are highly customizable in terms of color.

Corrosion resistance is another critical factor to consider when assessing a window crank longevity, especially if you live near coastal areas where the air is moist and has a high salt content. Materials like aluminum, brass, and stainless steel resist the elements well, ensuring that your casement window crank retains their functionality and aesthetic appeal over time.

Window Opening Mechanisms – Types of Window Operators

While sometimes you have to replace just the handle, other times you may need to reconsider the entire casement window opening mechanism. In this case, you may want to look for a crank handle set, which includes the handle, the cover, and the window operator. Now, this is the challenging part – there are different types of window operators, so you’ll have to check the existing one to replace it with another of the same type.

As such, there are several types of window operators:

  • a single-arm operator
  • a dual-arm operator
  • a split-arm operator
  • a dyad operator

The best thing you can do to make sure you get the correct operator is to look for an inscription on the existing operator indicating its manufacturer. If you can’t find one, you’ll have to rely on its form and mechanism to choose a new crank operator.

Installation: DIY Tips for Window Cranks

Although it may seem difficult at first, especially if you’ve never done this before, replacing a casement window crank is quite a straightforward task. The most important thing you should pay attention to is getting a crank handle (and operator, if needed) that fits your window.

Today, we’ll tell you how to replace a dual-arm operator on a casement window.

  1. Push the window open to free the bushing from the track.
  2. Next, you’ll have to remove the retaining clip that attaches the operator to the window sash.
  3. To do so, loosen the screws of the hinge that the operator is attached to.
  4. Then, remove the mounting screws that fix it to the window frame. If some screws are covered by the frame, you’ll have to remove it to loosen the screws.
  5. Remove the crank mechanism from the frame.
  6. Remove the clip that keeps the operator attached to the hinge.
  7. Use the clip to attach the new operator to the hinge.
  8. Slide the mechanism back through the opening in the window frame.
  9. Fix one arm into the sliding track.
  10. Rotate the crank handle to get the second arm in the required position to attach it to the sash.
  11. Install the screws to fix the operator to the window frame.
  12. Add the crank cover if you have any.
  13. Add the crank handle by using a screwdriver if it has a screw or just by pushing it onto the spline if it’s a snap-on handle.
  14. Open and close the casement window to check if the crank mechanism operates as intended.
  15. If you only need to replace the crank handle, use a screwdriver to loosen the screw if it has one. If it doesn’t, just use the screwdriver to pop the handle up. Replace the handle.

Tired of Replacing or Repairing Cranks? Get Crankless Magic Windows!

Crank mechanisms have been around for ages, being praised countless times for their ease of operation. However, cranks have long become outdated and unreliable given current advancements in the window industry.

Crank casement windows are prone to malfunctioning long before they reach the end of their expected lifespan. Why? Because, over time, the crank mechanism causes structural and functional issues. Since it only opens the sash by moving it from the bottom, the top is never actually controlled. It just responds to the movement from the bottom. Over the years, you’ll notice that this uneven motion will cause the sash to sag, warp, and bow. The heavier the window (triple-glazed windows, for example), the more pronounced the problems are, and, over time, they will lead to other structural issues.

Not to mention that crank mechanisms need to be replaced or at least repaired frequently – which is why you’re probably reading this article in the first place. Replacing one crank is not an issue, of course. But if you have, let’s say, ten or twenty windows in the house whose cranks need to be replaced frequently, the narrative changes.

How Are Magic’s Crankless Casement Windows Operated?

Magic experts decided to solve all these issues. How? By removing the crank mechanism altogether. We’ve designed the Parallex hardware system that makes our windows twice as durable and improves their performance and functionality.

So, how do our casement windows work without a crank? They have a galvanized steel rod that runs through the sash. It connects two shoes in the tracks at the top and bottom of the window frame. The sash is then fixed to these tracks, so when you open the window, it slides seamlessly along the tracks. The sash remains fixed to the frame at the top and bottom, and both window parts move in tandem. This system completely eliminates the risk of sagging, warping, or distortion.

Frequently Asked Questions

What are the different types of crank open windows?

There are two types of crank windows: awning windows and casement windows.

What’s the difference between a casement window and an awning window?

Casement windows open like a door, being hinged on the side, while awning windows open outwards from the bottom, being hinged at the top. Both allow natural light in, but casement windows excel in terms of unobstructed views.

Can I replace just the handle on my window crank if it’s damaged?

Yes, you can replace just the handle on a window crank if it’s damaged. This can help maintain functionality without replacing the entire mechanism.

Why should I choose metal cranks over plastic ones?

You should choose metal cranks over plastic ones because they are more durable and resistant to corrosion.

What type of window crank is suitable for high or hard-to-reach windows?

You can add an extension to the crank handle of a high or hard-to-reach window.

How do I know which window operator to choose for my casement or awning windows?

To find a suitable window operator, check the existing one and count the number of arms you see when the window is open. You can also look for the brand name on the existing operator. This way, you’ll find a replacement much easier.
