The maximum recommended length is 120cm, but over about 100cm (depending on the curtain weight) you're likely to need a support bracket (our code 648). For lengths over 120cm we recommend a portiere rod, or a curtain pole and brackets.
We make the dormer rods to measure and need the total length of the rod, from the end of the button finial to the centre of the hinge, as illustrated below. (The hinge is 180mm high x 40mm wide.) Rings can be purchased by clicking on 'Add Product Options'. We suggest 1 ring every 8 to 12cm, so you may wish to adjust the number of rings if your dormer rod is shorter than 64cm or longer than 96cm.
