Custom Leader Boxes

What Are Custom Leader Boxes?

A custom leader box, also known as a scupper box, rain collector, conductor head or collector box, is a vital component of a functioning rainwater drainage system. Installed at the top of a downspout, leader boxes help drain excessive rain by collecting runoff from the gutter system and directing it safely away from the roof and foundation.

Beyond their practical function of improving rainwater management, custom leader boxes serve as an architectural accent. Whether for historic restorations, modern designs or custom luxury homes, a well-crafted leader box is a decorative piece that showcases style and attention to detail.

At Salvo Metal Works, we manufacture custom leader boxes in a variety of styles, sizes and finishes at our location in Naperville, IL. Designed to match existing downspouts, gutters and rooflines, our handcrafted leader boxes ensure both performance and aesthetic appeal.

Benefits of Custom Leader Boxes

Efficient Rainwater Management – A leader box helps control the flow of rainwater, preventing water stagnation and foundation damage. By acting as a rain collector, it ensures water is directed safely into the downspout system, reducing the risk of overflow and leaks.
Prevents Water Damage & Ponding – Without a proper drainage system, excessive rain can lead to roof leaks, fascia board rot and masonry deterioration. Custom leader boxes provide a solution by regulating water flow and preventing ponding issues near the roofline and foundation.
Enhances Curb Appeal – More than just functional drainage components, custom leader boxes add a refined architectural touch to any building exterior. Available in round, square and decorative styles, they complement various architectural styles, from traditional copper-clad homes to modern metal roof designs.
Durability & Long-Lasting Performance – Crafted from high-quality metals such as copper, aluminum and zinc, leader heads are built to withstand the elements while maintaining their beauty and structural integrity.
Customizable to Your Project – Salvo Metal Works custom designs leader boxes to meet project specifications, ensuring a perfect fit for any gutter system. Our leader boxes can be tailored to match existing downspouts, scupper boxes and finials.
