Full extension soft-closing push-open with synchronize rail& clip 16/19board

Product Overview & Core Functions of Push-Open Undermount Drawer Slides

The TY310 series combines three functional systems — push-to-open actuation, hydraulic soft-closing, and a synchronization bar — into a single concealed undermount drawer slide platform. Engineered for handleless cabinet designs, the push-open mechanism allows users to open the drawer with a light press on the front panel, eliminating the need for external handles or pulls. The integrated soft-closing damper engages automatically during closing, decelerating the drawer and bringing it to a controlled, low-noise stop.

A metal synchronization bar connects the left and right slides, ensuring both sides move in unison throughout the opening and closing cycle. This feature is particularly valuable for wide drawers where uneven force application could cause binding or misalignment. The clip-on mounting system enables tool-free attachment and removal of the drawer from the slides, which streamlines both initial assembly and post-installation servicing. Constructed from galvanized steel with a 35kg per-pair load rating, this model supports eight standard lengths from 350mm to 700mm and fits both 16mm and 19mm drawer side panels.

	Push-to-Open Mechanism The push-open system uses spring-loaded trigger assemblies built into the front of each slide. A firm press on the closed drawer front releases the catch, and the mechanism propels the drawer forward by approximately 25mm, providing enough protrusion for the user to grasp and pull the drawer fully open. This function supports handleless furniture designs including modern kitchen cabinets, vanity units, and flush-front office storage.
Soft-Closing Damper System The hydraulic soft-closing damper activates during the last segment of the closing stroke, gradually reducing drawer speed before it reaches the fully closed position. This prevents slamming and reduces impact noise in commercial and residential environments. The damper works in coordination with the push-open catch, ensuring the drawer seats fully into the locked closed position after each closing cycle.
	Synchronization Bar for Wide Drawers The aluminum synchronization bar spans between the two slide units, mechanically linking their movement so both sides extend and retract at the same rate. This prevents skewed travel that can occur on wide drawers when force is applied off-center. The bar length is calculated based on cabinet inner width using the formula LA = LW - 330 ± 2mm, allowing precise sizing for each cabinet configuration.

Available Length Models

Note: The original product datasheet lists reversed drawer length values for the TY310-450 and TY310-500 models. The table above presents the logically consistent sequence where drawer length increases proportionally with nominal slide length, as is standard across the furniture hardware industry.

Installation & Drilling Dimensions

Drawer side mounting holes measure φ6mm with 11mm depth (φ6 H11). Key dimensional references include 11.5mm horizontal setback, 33mm rear spacing, and 13mm bottom offset from the drawer underside.

For width calculations, drawer width (SKW) equals cabinet inner width (LW) minus 42mm for 16mm panels, or minus 49mm for 19mm panels, with a tolerance of ±1.5mm. The synchronization aluminum rod length (LA) is calculated as cabinet inner width minus 330mm with a ±2mm tolerance. Minimum cabinet inner width is 7mm on the front side and 3mm on the rear side. Vertical mounting dimensions include 27.5mm minimum height, 37mm total depth, 12mm front offset, and maximum panel thickness accommodation of 16mm or 19mm with corresponding 21mm or 24.5mm front profiles.

The drilling hole pattern along the slide length starts 37mm from the front edge, followed by sequential intervals of 32mm, 96mm, 64mm, 32mm, 32mm, 32mm, 32mm, and 64mm corresponding to the 350mm through 700mm length increments. Both standard external drawer and inner drawer mounting configurations are supported. Inner drawer installation adds an X-dimension offset with X+37mm depth adjustment from the cabinet front.

Material & Build Specifications of Galvanized Steel Drawer Slides

The slide rails are stamped from galvanized steel sheet, providing corrosion resistance suitable for typical indoor furniture environments including kitchens, bathrooms, and office spaces. The galvanized finish maintains uniform appearance across production runs and requires no additional surface treatment. The telescopic triple-rail structure delivers full extension travel while preserving lateral rigidity across the complete 35kg load rating.

The push-open trigger assemblies incorporate precision coil springs calibrated for consistent actuation force. The soft-closing damper units use hydraulic oil with controlled viscosity for predictable deceleration performance across normal operating temperatures. The synchronization bar is manufactured from extruded aluminum for light weight and torsional stiffness, connecting to each slide via integrated coupling brackets. The plastic clip-on mounting components are engineered for repeated attachment and release cycles, supporting maintenance and drawer removal without tools.

Suitable Applications for Commercial Cabinet Hardware

This slide series targets furniture manufacturers producing handleless kitchen cabinetry, contemporary bathroom vanities, high-end residential wardrobes, and commercial office storage systems. The push-open function aligns with current minimalist design trends in kitchen and furniture design, where flush drawer fronts without visible hardware are a specified product feature.

For kitchen manufacturing operations, the synchronization bar makes this model well suited for wide pot drawers, pantry pull-outs, and island storage units where drawer width exceeds standard side-mount slide stability thresholds. Commercial procurement teams working on hospitality projects, multi-unit residential developments, and office furniture contracts can specify this model for handleless design packages. The clip-on installation system supports modular assembly workflows and simplifies field replacement during warranty servicing.

Mounting Instructions

Begin by calculating the required synchronization bar length using the cabinet inner width dimension, and verify that the selected slide length corresponds to the available cabinet depth per the size chart. Mount the fixed slide rails to the inner cabinet sides following the specified drilling pattern for your slide length, ensuring left and right units are aligned at equal height. Attach the synchronization bar between the two slides using the integrated coupling points.

Install the drawer-side mounting clips to the underside of the drawer box at the designated front and rear positions. The drawer then clips onto the slide assembly with a downward press, engaging the locking mechanism. For final alignment, adjust the front clip height to achieve uniform gaps around the drawer front panel. Inner drawer installations require the additional X-dimension offset for both depth and height positioning. After installation, cycle the drawer through multiple open-and-close sequences to verify push-open actuation, synchronized travel, and soft-closing performance.

FAQ

How does the push-open function work with soft-closing?

The two systems operate sequentially. Pressing the closed drawer front triggers the push-open spring mechanism, which ejects the drawer forward for access. During closing, the hydraulic soft-closing damper engages in the final stroke, slowing the drawer until it seats fully into the closed position where the push-open catch re-engages.

What is the purpose of the synchronization bar?

The synchronization bar mechanically links the left and right slides so they move at identical speed. This prevents the drawer from binding or traveling crookedly, which is especially important for wider drawers where users may apply force off-center.

What drawer width range does this model support?

Drawer width is determined by cabinet inner width. Use the formula SKW = LW - 42mm (for 16mm board) or LW - 49mm (for 19mm board), with ±1.5mm tolerance. The synchronization bar is sized accordingly using LA = LW - 330 ± 2mm.

Are the clips compatible with both 16mm and 19mm panels?

Yes, the clip-on mounting system is adjustable to fit both 16mm and 19mm drawer side panel thicknesses, which are the dominant standard sizes in furniture manufacturing. This allows consolidation of component inventory across product lines with different panel specifications.
