More and more homeowners are looking for composite doors that combine traditional aesthetics with reliable locking systems.
That’s why we offer the Heritage Plus Lock as part of our lock range, a smart solution from Winkhaus to complement Rockdoor designs like the Newark and Jacobean.
The Heritage Plus Lock is just one of the ways we’ve made Rockdoor stronger and more suited to your personal taste. If you’re looking for a front door that blends traditional charm with 21st-century security, this lock is the perfect finishing touch.

The Heritage Plus Lock is all about balance. On the outside, it offers the timeless appeal of traditional door ironmongery. But on the inside? It’s built with modern, robust mechanics to keep your home secure, day and night.
Whether you're upgrading a period property or just love the classic look, this lock helps your door stay true to that heritage style, without sacrificing safety or strength.

One standout feature is the centre-positioned hookbolt. Many locking systems raise the keyhole and deadbolt higher up the door, which can compromise both the visual appeal and structural integrity.
With the Heritage Plus, the hookbolt remains central—exactly where it would have been on classic timber doors. Not only does this keep the style authentic, but it also holds the door more securely in place and helps reduce any movement over time

The Heritage Plus Lock offers more than just traditional styling; it also makes daily life easier. It can be combined with slam lock functionality, which means the door locks automatically as soon as it’s closed. There's no need to lift the handle, giving you peace of mind that the door is always secure.
For added flexibility, there’s also an optional switch latch. It uses a spring-loaded latch bolt that extends from the edge of the door into a strike plate on the frame, keeping the door closed even when it’s not fully locked. A small switch or lever lets you choose whether the door stays latched or opens freely. This feature comes in handy for times when you want quick access without unlocking the door.
