Pallet Rack Identification Guide
Learn to Distinguish Between Teardrop, Structural, and Other Rack Types
Your Guide to Pallet Rack Identification
Pallet racking forms the backbone of the modern warehouse, maximizing storage space while allowing safe access to inventory. While they may look similar, each system has a unique structure, from the type of steel used to the shape of the connection points. Knowing what style you have is crucial for maintenance, sourcing parts, and planning upgrades.


How to Identify Your Pallet Rack
The most reliable method for identifying your pallet rack brand and style is to examine the connection between the upright frame and the horizontal beams. The size and shape of the punch holes in the upright column are the key identifiers. For additional guidance, check our Pallet Rack Buying Guide.
- Pay close attention to the shape of the holes (e.g., teardrop, keystone, round, slotted).
- Note the spacing between the holes, typically measured in inches on-center.
- Be aware that components from different styles are often not compatible.
Common & Interchangeable Styles: Teardrop
Teardrop is the most common and versatile style in North America. Originally patented by Interlake, its design is now used by hundreds of manufacturers, making parts easy to find.
Old Style Teardrop
The original design featuring a classic, rounded upside-down teardrop shape. Beams from new styles often fit.

New Style Teardrop
Features more rectangular holes with a slight taper. Often specific to the Interlake brand and not cross-compatible.

Mecalux Punched
A unique, bolted version of the teardrop style from Mecalux, designed for compatibility and flexibility.

Other Major Pallet Rack Styles
Beyond Teardrop, several other popular styles are defined by their unique, often proprietary, connection systems. Discover more about our Double-Deep Pallet Racking.

Keystone (Republic Style)
Identified by its distinctive trapezoid or keystone-shaped holes. This boltless system uses clip hooks for a high strength-to-weight ratio.
Ridg-U-Rak (Slotted)
Features a unique hook-and-slot connection with six-bend, roll-formed columns for exceptional rigidity and strength.
Speedrack
Known for its tubular steel design and a dual-locking system of handle clips and J-hook pins to prevent beam detachment.
Structural Steel Racking
Unlike roll-formed racking, structural racks are made from hot-rolled C-channel steel and components are bolted together. This construction provides superior durability and a much higher load capacity, making it the preferred choice for demanding environments.
- Extremely durable and resistant to forklift damage.
- Ideal for harsh environments like coolers, freezers, and outdoor applications.
- Perfect for storing very heavy pallet loads or for high-traffic facilities.

💡 Pro Tip: When buying Used Pallet Racks, always bring a sample beam to test the connection with the uprights. Even racks that look similar, like different Teardrop styles, can have slight variations that prevent a secure and safe lock-in.
