3M70-0715-1029-4 - 3M Speedglas 9100 Replacement Headgear Suspension

Genuine 3M Speedglas 9100 Series Replacement Headband

The 3M Speedglas Headband 9100 (06-0400-51) is the official replacement suspension system designed specifically for the Speedglas 9100 series of welding helmets. When your original headgear becomes worn, damaged, or loses its tension, this assembly restores the stability and comfort that the 9100 series is famous for. Engineered with a deep understanding of human ergonomics, this headband is not just a strap; it is a sophisticated suspension system that actively works to reduce fatigue during long welding shifts.

One of the standout features of this headband is its ability to avoid pressure on the sensitive nerves, arteries, and acupressure points of the head. The design utilizes two adjustable crown straps which significantly improve stability compared to single-strap designs. This ensures that the helmet remains securely in place, even when the welder is moving their head rapidly or working in out-of-position scenarios. The back of the headband features self-adjusting twin pads that conform to the unique shape of the user's head, distributing the weight of the helmet/filter assembly evenly.

The smooth ratchet mechanism is located at the rear, allowing for precise sizing adjustments. This large knob is designed to be easily manipulated even while wearing heavy welding gloves, enabling on-the-fly tightening or loosening as needed. This part is compatible with the standard Speedglas 9100, 9100 Air, 9100 FX, and 9100 FX Air helmets. It is not compatible with the older 9000 series or the newer G5-01 series unless specified by 3M adapters. Maintaining your personal protective equipment is critical for safety and performance; replacing the suspension ensures your auto-darkening filter remains properly positioned in front of your eyes.

Key Technical Benefits:

• Stability: Dual crown straps prevent the helmet from wobbling.


• Compatibility: Fits the entire 9100 family of shells.


• Durability: Constructed from high-strength industrial plastics designed to withstand the rigors of a welding environment.
