The stainless steel telescopic ladder with four rungs and a closure, 178 mm wide, is designed to provide a secure, compact boarding solution for vessels with narrow platforms. Made from AISI 316 stainless steel, it resists marine corrosion and wear from continuous use. Its telescopic design allows smooth extension and compact storage, while the closure system keeps the ladder secure while underway. With four non-slip rungs across a narrow 178 mm width, it provides a stable, ergonomic ascent from the water in confined spaces.
