These black iron casement stays will give any window a face-lift and they will last a lifetime. Many of these casement stays have been hand cast in a British foundry using traditional methods which are over 100 years old. Cast iron products have been familiar to the general public for many years. However, there are many varieties of cast irons all of which have different properties and applications. Malleable iron is particularly suitable for the production of builder's window architecture because of their strength and durability. It should not be confused with cheaper imitations which are also available. We provide many styles and sizes for our casement stays as we appreciate that everyone's needs and tastes are different.
