Quick Answer
The SimXPro 40x120 profile is a versatile aluminum extrusion that can strengthen your rig's base, support heavy components, or serve as a building block for custom accessories. Its larger cross-section provides added stiffness where you need it most.
Why Choose 40x120 Over Other Profile Sizes?
When you're deciding on profile size for your sim rig, the 40x120 profile offers a balance of strength and weight. It's wider than a standard 40x40 profile, providing more rigidity along one axis, which is ideal for applications like pedal plates or upright supports where flex is a concern.
Compared to a 40x160 profile, the 40x120 is lighter and often more affordable, making it a practical choice for many rig builders. However, if you're planning a very tall or heavily loaded structure, you might need the extra stiffness of a larger profile.
Where Can You Use 40x120 Profiles?
The 40x120 profile excels in areas that require extra strength without excessive bulk. Common uses include reinforcing the main chassis rails, creating a sturdy pedal deck, or building a monitor stand that can support heavy displays without wobble.
Because the profile is available in various lengths, you can cut it to fit your specific rig design. This makes it a flexible option for both upgrading an existing rig and building a custom cockpit from scratch.
Frequently Asked Questions
- Can I use 40x120 profiles to strengthen my existing rig?
- Yes. Replace or reinforce the main horizontal rails of your rig with 40x120 profiles to reduce flex, especially if you have a high-torque direct drive wheel or heavy pedals. Measure your current rig's rail length before ordering to ensure a proper fit.
- What is the best way to cut 40x120 profiles?
- Use a miter saw with a carbide-tipped blade designed for aluminum. Clamp the profile securely and cut slowly to avoid burrs. Deburr the edges with a file for a clean finish. Always wear safety glasses and gloves when cutting aluminum.
- Can I build a complete rig using only 40x120 profiles?
- Yes, but it's not the most common choice. The 40x120 profile is heavier and more expensive than 40x40 or 40x80, so a full rig may be overkill. It's best used for key structural components rather than every part. Consider a mix of profile sizes for optimal balance of cost, weight, and strength.
