Canberra Thin-Type Two-Section Concealed Drawer Slide (Latch Pin Version)

Structural Features
Upper Rail: Attached to the bottom of the drawer, the upper rail is engineered with a slim profile (typically 2-3mm thinner than conventional two-section slides) to minimize space occupation. It houses a precision wheel or ball-bearing assembly and a built-in latch pin slot, which works with the lower rail to enable smooth sliding and secure locking.
Lower Rail: Mounted on the inner base of the cabinet carcass, the lower rail is structurally matched to the upper rail. It features a corresponding track for the upper rail’s wheels/balls to roll on, ensuring stable drawer movement. A key design element is the latch pin receptacle—when the drawer is fully closed, the latch pin from the upper rail engages with this receptacle, locking the drawer in place to prevent accidental opening.
Latch Pin Mechanism: The core safety component, the latch pin is a spring-loaded metal pin integrated into the upper rail. When the drawer is pushed to the fully closed position, the pin automatically pops into the lower rail’s receptacle, creating a secure lock. To open the drawer, a slight outward pull overcomes the spring tension of the pin, disengagement occurs, and the drawer can be smoothly extended.
Slim Profile Design: With an overall thickness of usually 8-12mm (depending on the model), the slide occupies minimal vertical space between the drawer and cabinet base. This design maximizes usable drawer space and is ideal for cabinets with limited internal height.
Core Advantages
Concealed Aesthetics: When the drawer is closed, the entire slide system is hidden between the drawer bottom and cabinet base—no hardware is visible from the front, side, or top. This creates a clean, minimalist look for furniture, aligning with modern interior design trends.
Secure Latch Function: The spring-loaded latch pin prevents the drawer from sliding open accidentally, even if the furniture is jostled (e.g., during moving) or used in environments with vibration. It also adds a basic child-safety layer, reducing the risk of children pulling open drawers unintentionally.
Smooth & Quiet Operation: Equipped with high-precision plastic rollers or small-diameter steel balls (3-4mm), the slide minimizes friction between the upper and lower rails. This ensures the drawer opens and closes with minimal effort, without jitter, sticking, or harsh noises—enhancing the user experience.
Space Optimization: The thin structure and two-section design support full extension (the drawer can be pulled out completely from the cabinet), allowing easy access to items stored at the back of the drawer. Compared to partial-extension slides, it improves space utilization by 15-20%.
