A single niche holds one cremation urn. A companion niche is a wider or deeper compartment designed to hold two urns, allowing a married couple or family members to be interred together in the same location. CMV Fabrication manufactures both configurations and can produce columbarium layouts that mix single and companion niches within the same structure.
Companion niches are typically purchased in advance by one member of a couple, with the second interment taking place at a later date. The niche must be accessible for that second placement without disturbing the first urn. CMV Fabrication designs its companion niches with this requirement in mind, providing interior clearance and a faceplate system that allows reopening for the second interment.
