Reliable Shelving Hardware

Maximizing Cabinet Utility with High-Strength Support Pins

Consistency in hardware is vital for maintaining a professional standard across your production line. We provide shelf supports that feature durable finishes and robust designs to prevent shearing or slipping under heavy loads. These products are selected for their ease of installation and long-term reliability, ensuring that shelves remain level and secure throughout the life of the cabinet. By sourcing your shelf pins and sleeves alongside your core sheet goods and fasteners, you benefit from a consolidated supply chain that ensures your shop is always equipped with the most dependable hardware available to the trade.

Precision Engineered for Standard 5mm and 3mm Boring

Our shelf supports are designed to integrate seamlessly with standard industrial boring patterns, including the common 32mm system. Available in both 5mm and 3mm diameters, these pins provide a snug, rattle-free fit that is essential for high-quality casework. For shops looking to provide an extra level of durability, we also offer metal sleeves and grommets that protect the integrity of the boring holes in softer substrates like particle board. This precision ensures that end-users can adjust their shelving without damaging the cabinet gables, maintaining the structural and aesthetic quality of your work for years to come.

Different shelving applications require different levels of support, and our range is designed to cover every scenario.

Many of our supports feature anti-slide designs or integrated suction cups for glass shelving, providing added safety and stability. This versatility allows shop owners to standardize their hardware inventory while still being able to meet the specific technical requirements of complex architectural millwork projects.

Technical Guidance for Shelf Support Selection

Choosing the right pin type and material is essential for safety and ease of use. Below are the most common questions regarding our shelf support and pin products.

While capacity can vary by design, a set of four standard 5mm steel shelf pins is generally rated to support between 40kg and 60kg when installed in a quality substrate like MDF or plywood. For heavy-duty commercial storage or exceptionally wide shelves, we recommend using supports with a larger surface area or integrated screw-fixings to prevent the pins from crushing the hole edges.

Metal supports are the industry standard for durability and high-end aesthetics, offering superior shear strength and a professional look. Plastic supports are often used in high-volume production or when a locking feature is required to hold the shelf in place during transport. Both materials are effective, but for commercial casework where longevity is the primary concern, metal pins are typically the preferred choice.

Loose pins are usually the result of oversized boring or worn-out drill bits. Using high-quality carbide-tipped bits ensures a crisp, accurate 5mm hole. For an even more secure fit, you can utilize pins with a "ribbed" shank or install metal sleeves (grommets) into the holes, which provide a tighter mechanical grip and prevent the hole from enlarging over time with repeated adjustments.

Yes, we offer specialized shelf supports designed specifically for glass. These typically feature a soft plastic or silicone insert, or a small suction cup, that provides a non-slip surface and prevents the glass from scratching. Using the correct support for glass is vital for safety, as it prevents the shelf from sliding forward or shifting within the cabinet box.

The 32mm system is an international standard that simplifies the manufacturing process by using a consistent distance between holes. This allows for total modularity, meaning that shelf pins, drawer slides, and hinge mounting plates can all be installed using the same boring pattern. Standardizing your shop to this system increases production speed and ensures that all internal hardware is perfectly aligned every time.
