The From the Anvil Deluxe Locking Monkeytail Window Fastener is a traditional style fastener inspired by 18th century design. It’s made from solid brass and features a durable, safety-tested shank.

This style makes use of a rolling friction latch on the back of the bolt that allows for a simple locking mechanism, and the handles are nailed to the framing to hold the window securely in place.
