Fireball Tool 1826 Combination Square
The Fireball Tool 1826 Combination Square takes the versatility of a traditional combination square and gives it a larger, more fabrication-friendly design.
Precision-machined from solid aluminum, the 1826 provides accurate 45° and 90° reference surfaces for layout, measuring, marking, and fabrication work. Its oversized body gives you more surface area to register against tubing, plate, and larger workpieces, making layout fast and easy around the welding table or fabrication shop.
Add a Fireball Tool measuring blade for adjustable measurements and layout—or use the 1826 completely on its own as a standalone square.
Small combination squares are great for small work. Once you start working with larger tubing, plate, frames, and fabricated assemblies, a larger reference surface can make the job considerably easier.
Fireball designed the 1826 Combination Square to give you that extra working area while keeping the tool lightweight and easy to handle.
Use it for:
Checking 90° corners
Marking 90° cut lines
Laying out 45° angles
Welding and fabrication layout
Square and rectangular tubing
Plate and flat bar
Frame fabrication
Measuring and marking material
Shop and machine work
General metalworking and layout
The 1826 gives you two of the most commonly used angles in fabrication:
45°
90°
Use the machined reference surfaces to quickly mark material, check an assembly, or establish a reliable angle during layout.
For welders and fabricators, that makes it a useful tool to keep close to the welding table for everything from quick cut marks to larger project layouts.
The square body is precision-machined from solid aluminum, providing a combination of accuracy, durability, and manageable weight.
Aluminum keeps the tool easy to handle despite its larger size, making it practical for everyday use around the shop.
One of the biggest advantages of the Fireball Tool design is that the square doesn't depend on a ruler blade to be useful.
Remove the blade and the 1826 remains fully functional as a standalone square.
That gives you two tools in one:
Use it as a traditional adjustable combination square when a blade is installed, or grab the body by itself when you simply need a large 45° or 90° reference.
The 1826 works with Fireball Tool measuring blades, allowing you to configure the square around the type of work you do.
Fireball currently offers compatible blade lengths including:
12"
18"
24"
300mm
450mm
600mm
This gives you the flexibility to build a compact measuring setup or add a longer blade when working with larger material.
Fireball Tool offers two versions of this combination-square design:
The 1826 uses the narrower 1" body design and provides a large, versatile square for everyday fabrication, layout, and measuring.
The larger 3827 version provides an even wider 3" body for applications where additional reference surface is useful.
Choose the size that best matches the scale of your fabrication and layout work.
One of the defining features of the Fireball Tool Combination Square is its size.
The larger body provides more surface area for registering against the workpiece, making it particularly useful for large tubing, plate, frames, and fabrication projects where a small layout square can feel undersized.
You get the fast 45° and 90° references you'd expect from a speed square, combined with the versatility of an adjustable combination square when paired with a Fireball Tool blade.
