The "Mast Step" is manufactured from a special combination of "Nylon/Glass fibre" which together with its design gives the step enormous strength. With a 3% additive, it makes the mast step UV resistant and prevents material degradation. The steps weighs only 165grams each (weight is always a consideration for products up a mast), and when folded does not snag ropes or sails due to the 'snag-free' design. At anchor or on a mooring the steps do not rattle in the wind.
