MSA45 - Strong Hand Adjust-O Magnetic Square with On/Off Switch

Precision Magnetic Fixturing with the Strong Hand MSA45

The Strong Hand Tools MSA45 Adjust-O Magnet Square represents a significant step forward in fabrication efficiency and safety. Designed for professional welders and fabricators who demand precision, this magnetic square integrates a functional On/Off switch that fundamentally changes the workflow of layout and fit-up tasks. Unlike traditional permanent magnets that are always 'live,' the MSA45 allows the operator to position the tool exactly where it is needed without the magnet fighting against the workpiece. Once the square is perfectly aligned, a simple turn of the switch engages the powerful rare earth magnets, securing the materials with up to 65 lbs (30 kg) of pull force.

This tool is engineered to hold a variety of stock shapes, including flat steel, square tubing, and round pipes, thanks to its thoughtfully designed V-groove and flat surfaces. The unit provides rigid holding at the most common fabrication angles: 45 degrees and 90 degrees. This versatility makes it an indispensable asset for creating frames, brackets, and complex assemblies where an extra hand is often required. The compact dimensions of 4-3/8" x 3-3/4" x 1" ensure that it fits into tight spaces without obstructing the welding torch or electrode access.

Maintenance and longevity are also key features of the Adjust-O design. Traditional magnets often accumulate metal filings and fuzzy iron dust that can be nearly impossible to remove completely, eventually compromising the accuracy of the tool. With the MSA45, cleaning is effortless: simply turn the switch to the 'Off' position, and the magnetic field collapses, allowing debris to fall away or be wiped off with a cloth. This feature ensures that the machined surfaces remain clean and true, providing consistent accuracy over the life of the tool. Weighing only 1 lb, it is lightweight enough for all-day use yet robust enough to withstand the harsh environment of an industrial welding shop.
