The PRIME-LINE PRODUCTS U 10166 is a metal shelf support peg designed to hold adjustable shelving in bookcases, cabinets, and similar casework. Each peg measures 0.875 inches long with a 5mm diameter pin, and features a nickel finish for corrosion resistance and a clean appearance. Sold in packs of 8, this part is suited for cabinet installers, millwork contractors, and maintenance technicians who need reliable shelf support hardware in quantity. The metal construction provides a stable bearing surface under load, making these pegs appropriate for both residential and light commercial cabinetry applications.
These shelf support pegs are commonly used in kitchen cabinets, bathroom vanities, office furniture, and built-in shelving units where adjustable shelf positioning is required. The 5mm pin diameter fits the standard 5mm shelf pin holes drilled in most manufactured cabinet carcasses. Each pack contains 8 pegs, making it practical for restocking or completing multi-shelf installations in a single order.
Designed as a replacement or supplemental shelf support peg for cabinets and furniture with standard 5mm shelf pin holes. Verify hole diameter and peg length against the existing cabinet specification before ordering.
Installation requires no special tools — pegs press or tap into pre-drilled 5mm holes in the cabinet side panel. Ensure all four support pegs for a given shelf are seated fully and at the same depth before loading the shelf. Inspect the cabinet panel material around each hole for damage or wear that could reduce holding strength. No power tools or fasteners are required for standard installation.
