Designed With Purpose: Spacious, Safe, and Scalable

Each cremation niche is deep enough to accommodate two upright urns, offering families a companion interment option. The powder-coated niche interiors also prevent metal urns from fusing to the niche interior over time — an essential feature to allow for companion urns to be repositioned further back when needed.

Need more space? The Trident’s modular design can be expanded in height or length, with additional niche rows or architectural elements.  Custom niche sizes are also available.
