🔍 SEO-Optimized Head Harness: Compatible with 3M 6000 Series and Trudsafe 6900 Series Review

I wear a mask every day and these unbranded straps lasted about a month before breaking at the ends when having to pull to tighten them. Rubber should be more durable.

The material of the strap does not withstand the stress of a metal loop and the constant stretching under load and movement. If you have to put the mask on, the strap will tear. 3M must choose the best material that can withstand the constant load in a given adjustment range.

This is almost the same as 3M's OEM suspension. I recommend one thing if you buy this. Retain the old hardware from the old wiring harness and replace the strap with this. The small round mounts for this strap are slightly larger than the OEM mounts and I struggled to fit them to my respirator. Sometimes I thought I could tear the respirator.
