Shelf Supports 13/16 inch 21mm Polished Brass describes a Sugatsune America support designed to hold shelving at a 13/16 inch, or 21mm, seating depth, which helps keep shelves consistently aligned in cabinets, closets, and similar storage projects. The polished brass finish provides a bright metal appearance, which suits projects where the support remains visible on open shelving runs or behind glass doors. Being part of the Shelf Supports product class keeps this part focused on doing one job in your layout: supporting wood or similar shelves at a precise depth. The CM30013 manufacturer part number ties the support to Sugatsune Americas catalog, which matters when matching existing hardware on a job or ordering repeat quantities for future builds.
The 13/16 inch (21mm) description defines how far this Sugatsune America shelf support engages under the shelf, giving installers a predictable bearing point when laying out cabinet or closet interiors. Because the part is classed as a Shelf Support, it is intended to work as the contact point between side panels and shelving, which helps streamline drilling layouts and spacing decisions across a project. Using the CM30013 identifier lets shops align their shelf drilling programs or jigs around a single support style, which supports repeatable fit from job to job.
This Sugatsune America CM30013 part sits in the Shelf, Closet & Garage Organization and Shelf Supports grouping, which positions it squarely for cabinet interiors, closets, and similar storage builds that rely on discrete support points rather than continuous cleats. The 13/16 inch (21mm) dimension describes the size relationship between the support and the shelf depth it engages, so once a shop standardizes on that dimension, it can repeat the same drilling pattern across uppers, bases, and closet panels. The polished brass finish lets the support function in projects where the hardware can be seen, such as adjustable bookshelves or display cabinets that benefit from a brass detail along the cabinet sides.
The polished brass finish on this CM30013 shelf support provides a uniform brass appearance, which helps maintain a consistent look when used alongside other brass-finished cabinet hardware throughout a project. Because the support is identified as 13/16 inch (21mm), it establishes a known seating depth for shelves, which helps reduce rework by giving installers a repeatable depth relationship from part to part. Using the Sugatsune America manufacturer part number CM30013 on drawings or cut lists ties the field installation back to a specific shelf support, which simplifies future replacements or additions when clients expand storage in matching cabinetry. Placing this support in the Shelf Supports product class keeps its role focused, so designers can clearly specify it wherever a discrete, polished brass shelf bearing point is needed.
