Introducing Super Fenders. The great defenders of property rights. BJ Marine Products MAIL FOR FREE BULLETINS. Name Title Company Address One good measure of bond strength and rubber greatness is a deflection test. Our Dock Fenders test out with a whopping 70% deflection. Still bonded, still with tons of energy absorp- tion power for more pro- tection. Super Heavy-Duty Modular Fenders. Steel mounting plates mean fast, strong welded installation. Installation and maintenance cost less. Replacement is less expensive, too —the damaged module or segment (it happens, you know) can be replaced individually. Choose from two basic styles that make up con- tinuous protective fenders. Customized to fit curves,too. Super Extruded Rubber Fenders. Choose from six basic shapes in lengths up to 20 feet. They can be pre- curved, with special modifi- cations for unusual needs. All six are easy to install, either suspended or bolted into place. BUT THAT'S NOT ALL, FOLKS!
