From The Anvil. Polished Brass Monkeytail Fastener

A cast Monkeytail Fastener which is reversible and therefore allows use on either left or right handed windows. Ideal for windows with a draught seal due to the Mortice Plate allowing the pulling of the window as far as the seal allows. Comes with a mortice plate for single windows & a hook plate for use with a central mullion. This product is cast from very high quality solid brass and is given a classic look with it's finish. All of our Polished Brass products are manufactured to the highest standards and come un-lacquered so to retain the original finish. Regular polishing with a good quality metal polish is essential. However, if the intention is to allow the surface to age through oxidization, no attention needs to be given. Over time the brass will acquire a darker and more aged patina. Sold as a set and supplied with necessary fixing screws. Finished in Polished Brass.
