Image Number 2 for United States Patent #5694668.
A double locking snap hook is provided with an extended hook shank and return portion to form a lengthened hook portion for use in conjunction with the assembly and disassembly of wall forms. A slot is provided in the hook shank through which may be inserted a strap made of webbing, leather or another sturdy, flexible material. This strap may in turn be connected to a worker's safety belt or harness, permitting the worker the use of both hands while securely attached to the wall form. In addition to other modifications, the return portion is narrowed somewhat to permit passage through the slots of the wall form bracing.
