The tractor beam power-generator trench represented one of seven spots linking the Death Star I's reactor to Docking Bay 327's tractor beam. It was in this trench, specifically within the Level 6 Core Shaft Corridor at Tractor Beam 12 of [Section N-Six],(/article/section_n-six) that Obi-Wan Kenobi disconnected the link, which then enabled the Millennium Falcon to make its getaway. Two stormtroopers were stationed at the corridor's entrance, but the Force was used by Kenobi to divert their attention.
