Abstract: A safety bottom bracket for a sectional door is provided. The safety bottom bracket includes a frame, a cable attachment member coupled to the frame for attaching a cable to the bracket, and a slot in the frame for securing the bracket to the sectional door via a fastener passing through the slot. The slot has a tool-accessible portion, and a tool-inaccessible portion defined by one or more protrusions extending from or near the edges of the tool-inaccessible portion of the slot. When the bracket is connected to the cable under tension, the bracket is biased to a tensioned position where the fastener is located in the tool-inaccessible portion of the slot. When the bracket is not under tension or when the bracket is not connected to the cable, the bracket is movable to an untensioned position where the fastener is located in the tool-accessible portion of the slot.
