The HB Series is ideal for protecting a ship s mooring lines from pier and/or chock abrasion and for protecting lines used for towing. Chafe-Pro s HB Series is constructed of multiple layers of FJORD s specially formulated and designed heavy-duty nylon weaves. The layering technique used in the HB Series is designed to provide maximum flexibility and ease of application, and also provide long chafe-resistant service. Typical application includes use in mooring/anchoring and towing operations.
