Fall protection anchor devices, systems, and methods

A fall protection anchor system for a double-section steep pitch roof, the roof defining two substantially planar steep pitch roof portions that meet at a ridge of the roof, the ridge extending perpendicular to a rafter that partially supports one or more of the roof portions, each roof portion defined by a roof pitch expressed as a ratio of a vertical rise divided by a horizontal span of that roof portion, the roof pitch ranging between 4:12 and 20:12, the anchor system comprising:

• an elongate anchor bar that defines an anchor point aperture extending through the anchor bar to define an anchor point operatively located above the ridge;
• a pair of anchor brackets, each anchor bracket:
• comprises a plate that defines a plurality of plate flanges, each plate flange extending in a corresponding plate flange plane, each plate flange plane substantially orthogonal to a plane defined by the plate, a first plate flange of the plurality of plate flanges operatively extending substantially vertically, a second plate flange of the plurality of plate flanges operatively extending substantially horizontally;
• defines a plurality of bracket plate apertures extending through its plate;
• defines a plurality of bracket flange apertures extending through one or more of its flanges;
• operatively attaches to a roof support via a plurality of fasteners that extend through the plurality of bracket plate apertures, the roof support comprising the rafter or a gusset, blocking, or bracing attached to the rafter;
• and
• operatively attaches to the anchor bar;
• wherein:
• the first plate flange of a first anchor bracket of the pair of anchor brackets and the first plate flange of a second anchor bracket of the pair of anchor brackets operatively fasten to each other and to the anchor bar;
• the anchor system operatively fastens the anchor bar at any of a plurality of elevations with respect to the anchor brackets after each anchor bracket is operatively attached to its roof support;
• the anchor bar operatively defines a vertically extending anchor bar height, an anchor bar width that is orthogonal to the anchor bar height, and an anchor bar thickness that is orthogonal to the anchor bar height and the anchor bar width, the anchor bar width defining a plane that is operatively substantially parallel to a plane defined by the ridge of the roof;
• the anchor bar operatively extends, through an opening in the roof, from an interior attic zone covered by the roof to above the ridge of the roof;
• and
• the anchor bar is configured to operatively connect to a fall protection system at the anchor point.
