From The Anvil. Antique Pewter 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 contemporary look with it's distinctive finish. This unique Antique Pewter finish is a complicated process applied to a solid brass base metal giving excellent anti-corrosion properties. It is a close match to our Pewter Patina finish but has a smoother and warmer, less traditional feel. Sold as a set and supplied with necessary fixing screws. Finished in Antique Pewter.
