Allen-Bradley 440E-A17105 Cable

Allen-Bradley 440E-A17105 Lifeline Rope Tensioner System with Allen Key is a safety accessory used with Rockwell Automation Guardmaster Lifeline systems to maintain proper tension on the lifeline rope in rope-pull emergency-stop configurations. The 440E-A17105 serves as the tensioning element in Lifeline setups, helping ensure a taut lifeline between fixed anchors and guide points so pull-wire switches actuate reliably along horizontal or overhead runs. The kit is documented as Lifeline tensioner and Allen key (440E-A17105) in Rockwell’s safety accessories lineup and is referenced on distributor pages and official cut sheets as the Lifeline tensioner component for Guardmaster Lifeline configurations. Common applications include machine guarding on automated production lines where consistent lifeline tension supports safe access and prompt emergency-stop actuation. The part is designed specifically for Lifeline rope systems and is associated with Guardmaster Lifeline safety configurations; installation varies with the chosen rope length and mounting arrangement, and the Allen key is used for initial setup and adjustments.
