The Selden 508‑185‑03 Foldable Mast Walker / Mast Step is a lightweight, high‑strength safety step designed for secure and comfortable mast climbing. Manufactured from Almag 35 aluminium alloy, it delivers excellent corrosion resistance without the need for anodising, ensuring long‑term durability in harsh marine environments. The foldable design keeps the mast profile clean when stowed, while providing a stable foothold when deployed. Each unit includes 3 stainless steel M6 × 15 mm screws suitable for mast wall thicknesses above 4 mm, making installation straightforward for most yacht rigs.
With a 15 × 3.5 cm rung, 11 × 7 × 2.4 cm bracket and a total weight of just 250 g, this mast step offers a strong yet unobtrusive climbing aid. Step spacing should be set between 40–50 cm, depending on user agility and leg length, to ensure safe and comfortable ascent. The maker avoids anodising these steps to prevent damage to the mast’s own anodised surface and because the alloy itself provides exceptional natural corrosion resistance, making it a dependable choice for sailors seeking a robust and practical mast‑climbing solution.
