These full extension undermount drawer slides combine a three-section concealed rail structure with a hydraulic soft-close system, designed for furniture requiring complete drawer access. The Eastmax TY301D series mounts beneath the drawer box, leaving side surfaces fully visible for a seamless furniture appearance. The tool-free clip-on mounting system with 3-dimensional adjustment supports fast installation and precise front alignment, addressing the efficiency and accuracy needs of furniture manufacturing and commercial fit-out projects.
Constructed from galvanized cold-rolled steel, the three-section rail assembly includes a fixed cabinet rail, a middle rail, and a moving drawer rail, all formed with uniform hole patterns for reliable mounting. The galvanized surface treatment delivers corrosion resistance for indoor cabinetry environments and maintains a consistent silver finish across production batches. The integrated hydraulic cylinder is positioned within the rail profile, protected from dust and impact during transport and installation. Each pair of slides is rated for a 35kg load capacity, covering medium to heavy drawer storage requirements in residential and contract furniture.
The hydraulic soft-close mechanism activates during the last portion of the closing stroke, gradually decelerating the drawer before it reaches the fully closed position. This controlled deceleration eliminates slamming noise and reduces wear on both the slides and the drawer box itself. The mechanism operates with consistent damping force across the full load range up to 35kg, ensuring uniform closing behavior whether the drawer holds light or heavy contents. The slide assembly is tested for 50,000 opening and closing cycles, providing a measurable durability reference for commercial procurement evaluation.
The TY301D full extension series spans eight nominal lengths from 260mm to 610mm, matching drawer depths commonly used in kitchen, wardrobe, and office furniture designs. The system is compatible with both 16mm and 19mm thick drawer side panels, and the clip-on brackets accommodate both thicknesses without separate adapter parts. Full extension travel allows the entire drawer interior to be pulled outside the cabinet, improving access to stored items and supporting ergonomic use in kitchen and workstation applications.

The clip-on locking system attaches the drawer to the slide assembly without screws or additional tools, allowing installers to seat and release the drawer by pressing the release tabs on both sides. The mounting clips provide three-directional adjustment — height, depth, and side-to-side — enabling fine tuning of drawer front alignment for uniform gap spacing across cabinet runs. This tool-free approach reduces per-unit assembly time and lowers the skill threshold required for on-site installation, which translates to measurable labor savings for furniture factories, joinery shops, and large-scale fit-out contractors. Typical applications include premium kitchen cabinets, built-in wardrobes, bathroom vanity units, office storage pedestals, and hotel room furniture.
Full extension indicates that the three-section rail structure allows the drawer to travel completely out of the cabinet, exposing the full interior depth. This differs from partial extension two-section slides, which leave the rear portion of the drawer inside the cabinet. Full extension designs are preferred for kitchen and storage applications where complete access to drawer contents is required.
The TY301D series supports both standard overlay and inset drawer configurations through the adjustable clip-on brackets. Installers can adjust the front position in depth and side directions to match the cabinet design, making the slides suitable for multiple furniture styles within a single production program.
The 35kg rating refers to the maximum evenly distributed load per pair of slides under normal operating conditions, based on standard furniture hardware testing methods. For drawers holding heavier items such as file storage or cookware, buyers should verify that total drawer weight, including the drawer box itself, remains within the rated capacity.
Yes, the clip-on mechanism allows tool-free drawer removal. Users press the release levers on both left and right clips simultaneously and pull the drawer forward to detach it from the slide body. Reinstallation follows the reverse process, with the drawer slotting back onto the clips until they lock into position. This feature simplifies cabinet cleaning, interior access, and on-site maintenance tasks.
