  • Patent number: 8635821
    Abstract: A safety line anchor securable to a roof drain is disclosed. The anchor provides a secure tie down location for people working on the roof of a building. The anchor is portable so that users can carry it with them to the roof and secure it in a roof drain with minimal modification of the drain. When the worker is finished on the roof, the device can be removed and carried away. The safety line anchor comprises a body, a drain coupling assembly, and an expansion assembly. The drain coupling assembly securely fastens the anchor to the roof drain. The expansion assembly expands in the neck of the drain or the roof drain system piping to minimize wobbling of the anchor. A safety line may be attached to the body of the anchor.
