Here at Merlin, we recognise that selecting the correct ironmongery for each door type can often be a complex and time-consuming process. To simplify this, we have developed our Prostyle Ironmongery Sets — a clear and structured approach that shows exactly what is required for every door function.
Our Prostyle Spider Diagram (below) provides an at-a-glance visual guide, detailing the complete set of components needed for each door type — whether it be a Latch, Sashlock, WC Lock, or Deadlock. Each pathway clearly illustrates the appropriate hardware, including lever sets, escutcheons, turns, pulls, and door closers, ensuring every element is accounted for.
By offering complete ironmongery sets, we remove the uncertainty and inconvenience of sourcing individual components. Each set is curated to ensure compatibility, quality, and visual consistency across all door types.
Choosing a Prostyle Ironmongery Set provides the following advantages:
Efficiency: All necessary items are supplied in one complete package.
Consistency: Every component is matched for finish and design integrity.
Simplicity: The clear diagram allows for quick identification of the correct set for each application.
Reliability: Each selection ensures compliance with performance and aesthetic requirements.
With Prostyle Ironmongery Sets, the specification and ordering process is streamlined — saving valuable time and ensuring a professional, cohesive finish throughout your project.
