both buckle ends 7 and 8 and subsequently tightening the strap 6 this pad attachment design allows for the use of non conductive materials such as plastic supports nylon straps and pads nylon thread and acetal snap fit buckles instead of the leather pads with metal rivets and metal buckles that are commonly used and which do conduct electricity fig1 shows the attachment of the gaff 3 to the hook 1 the gaff is provided with a projection which resides in a recess within the inside of the hook 1 as shown in hidden lines in fig1 the countersunk holes within the hook allow the flat headed fasteners 31 to be threaded directly into the gaff and rigidly secure the gaff 3 to the hook 1 the screws remain hidden below the interior surface of the hook and constitute a part of the insulation means to insulate the leg from the gaff if it were to come into contact with an electrical source fig1 and 16 show a portion of hook 1 that contains a high density polyurethane foam 34 shown in hidden lines the foam is used as a filler in the hook it is placed in the interior of the hook to allow for a consistent and continuous amount of composite material to be used throughout the entire hook 1 the use of foam decreases total part weight decreases cost and increases stiffness of the hook 1 all of the individual parts of the assembly are constructed of non conductive materials such as high strength composite materials thermoplastic urethane polyester and nylon the use of such synthetic.
