3M™ Protecta® Confined Space System

When it comes to confined space entry/rescue, it is essential that equipment operates perfectly and quickly. Lightweight, portable 3M™ Protecta® Aluminum Tripods are ideal for confined space manhole entry and retrieval. They’re easily transported from one location to another and can be set-up by one worker. Attach one or two mechanical devices such as a winch or 3-way self retracting lifeline and you’re ready to go. Our tripods are loaded with features such as locking legs, simple detent pin style adjustment, quick-mount mechanical device bracket, safety chain to prevent movement, and skid resistant tread plate soles on feet.
