The Trylon 4.98.S800.070 step-bolt climbing kit is designed for use on a 70ft SuperTITAN model S800 tower. It includes everthing you'll need to install the kit. The Trylon climbing step-bolt kits facilitate an easier climb up the tower and are available for all SuperTITAN tower heights and models. This kit contains 2 welded ladder sections and 5 screw-in bolt kits for attachment directly to the tower legs. For maximum safety, the step-bolts can be used in conjunction with the Cougar safety cable system. All parts of the 4.98.S800.070 are completely hot-dip galvanized for years of trouble-free service.
