The G-Mag is a magnetic guide tube clamp designed for industrial radiographers working with ferritic piping. It provides a fast and secure method for positioning guide tubes during contact radiography, eliminating the need for masking tape, Velcro straps, or other improvised mounting methods.
 
Its magnetic, articulating feet allow for precise and effortless placement and repositioning on ferromagnetic surfaces, without constraints. The clamp holds the guide tube firmly in place and is compatible with Sentinel-style fixed stop guide tubes.
 
The G-Mag is made from carbon fiber-reinforced nylon filament, chosen for its durability in harsh outdoor conditions and daily field use. It's built for radiography applications where repeatability, speed, and usability are critical.
 
No more tape wastage. No more rubber bands.
