Over Extension Drawer Slides

HA3504 Over Extension Drawer Slides

Over extension drawer slides are engineered to allow drawers to extend beyond their nominal length, providing enhanced access to the entire drawer space. Compared to standard full-extension slides, they make it easier to reach items stored at the back, improving efficiency in both industrial and professional environments. This feature is especially valuable where precision, accessibility, and space utilization are critical.

The HA3504 over extension double-layer ball bearing slide is designed to deliver reliable performance with a load capacity of 60 kg. Manufactured from high-quality cold rolled steel and featuring a 1.5*1.5 mm thickness, it ensures durability while maintaining a relatively lightweight structure. The double-layer design enhances stability and smoothness, making it suitable for frequent and consistent use.

With its advanced over extension structure, the HA3504 allows drawers to extend beyond the cabinet, ensuring full visibility and easy access to stored items. Available in sizes ranging from 12 to 28 inches (300mm–700mm), it fits a wide range of drawer dimensions. The non-detachable design adds structural integrity, reducing the risk of misalignment and ensuring long-term reliability.

This model is widely used in industrial drawers, toolbox cabinets, and medical equipment where precision and convenience are essential. Its smooth ball bearing operation, combined with stable load performance, makes it ideal for environments that require both durability and ease of use. The HA3504 over extension drawer slide is a practical solution for improving workflow efficiency and maximizing storage accessibility.
