Telescoping post anchors and components work together to create a davit system used to arrest falls and raise and lower workers over edges or into confined spaces. They accept extensions and attachments (such as davit arms) to protect against vertical fall hazards. Posts attach to a base that is permanently mounted to a secure surface. The post can be moved and attached to another base as needed. Workers wearing a fall protection harness and lanyard or self-retracting lifeline (SRL) connect the lanyard to the anchor. A horizontal lifeline can be strung between two posts.
