Please select that you need items cut to length, if not you will be supplied multiples of that length.This doesn't apply to one length, only on jobs where you'd need several of the same length, for example 6 / 1800mm would be 3 / 3600mm if you do not need them cut to length.
Please Note: 1 x Centre Stringer (sold separately) is required for every 1200mm span. (ie. if your stairs are 3600mm wide you will require 2 Saw Tooth Centre Stringers.)
