5mm shelf support from Knape and Vogt provides a compact way to hold cabinet or closet shelves using a pin sized for common system holes. The 4.7 mm pin diameter fits a 5 mm hole, so it seats snugly without excessive play in standard line-bored panels. The pin length of 5/16 inch, or 8 mm, keeps the support anchored in the side panel while leaving the body exposed to carry the shelf edge. A body size of 1/2 inch, or 13 mm, wide by 11/16 inch, or 17 mm, long gives the shelf a defined bearing surface at the corner. The plastic, zinc, and steel construction pairs structural metal with formed detail, so the support can present a shaped edge to the shelf while the metal core carries the load. The nickel-plated finish provides a clean metallic look at open shelf ends where supports remain visible after installation.
The 4.7 mm pin diameter is specified for use in a 5 mm hole, so it matches common system boring patterns in cabinet and closet construction. With a pin length of 5/16 inch, or 8 mm, the support engages the side panel without reaching too close to the panel face, which helps maintain clearance around the front edge. The 1/2 inch by 11/16 inch body dimension defines how far the support projects into the cabinet space, letting layouts around face frames or doors account for the support body as shelves slide into position. The plastic, zinc, and steel construction with nickel-plated finish aligns with other metal hardware in system-built cabinets.
The Knape and Vogt 345 NP shelf support is specified for 5 mm hole systems, so it fits cabinets or closets bored for 5 mm pins using standard line-boring equipment. The 4.7 mm pin diameter allows the support to sit firmly in those holes, which helps keep repetitive shelf positions consistent across multiple cabinets. With a pin length of 5/16 inch, or 8 mm, the support is suited to typical side panel thicknesses where the pin can seat fully without extending through. The 1/2 inch width and 11/16 inch length place the bearing surface under the shelf corner, which suits adjustable shelving in casework where the front edge needs a defined rest point. The plastic, zinc, and steel build with nickel-plated finish works in residential or light commercial cabinet interiors where metal shelf supports are standard.
The 5mm shelf support sizing ties directly to a 5 mm hole layout, so once the side panels are bored, each 345 NP shelf support locates in the same way along the pattern. The 4.7 mm pin diameter keeps insertion straightforward while limiting side play, which helps the shelf stay square when multiple supports share the load. With an 8 mm pin length, the support grips enough material in the cabinet side to resist rocking as shelves are loaded and unloaded. The 1/2 inch by 11/16 inch body provides a consistent footprint, so finished shelf lengths can be cut for a repeat overhang beyond the support. The nickel-plated finish on the metal elements adds a uniform appearance along cabinet interiors, which is useful when many supports are used on open or glass-fronted shelving.

The shelf support body measures 1/2 inch, or 13 mm, wide by 11/16 inch, or 17 mm, long, giving the shelf a defined bearing area at each supported corner.
The 345 NP support is made from plastic, zinc, and steel with a nickel-plated finish, combining metal load-carrying parts with formed components and a uniform surface.
The Web Description notes use with KV129 rubber cushion, which adds a layer between the support and the shelf underside when that detail is part of the installation.
