FAQ

Frequently Asked Questions about Soft Close Concealed Drawer Slides

❓ What is the difference between 1D and 3D brackets for Model 25.303?

The 1D bracket provides vertical adjustment only – it’s a cost-effective solution for standard production runs. The 3D bracket allows adjustment in three dimensions: vertical, horizontal (side-to-side), and depth (in/out). This enables perfect alignment of drawer fronts after installation, ideal for custom cabinetry or high-end kitchens where aesthetics are critical.

❓ Can these undermount drawer slides be installed on existing drawers?

Model 25.303 is designed for new drawer construction, as it requires specific routing/grooves in the drawer bottom and sides. However, if you have flat-bottom drawers with sufficient clearance, retrofitting is possible. We recommend consulting our technical datasheet or contacting support for your specific application.

❓ What is the maximum drawer width for 45kg soft close slides?

For optimal performance at 45kg capacity, we recommend drawer width not exceeding 1200mm. Wider drawers may experience racking (twisting) under load. For extra-wide drawers, consider using two sets of slides or contacting us for heavy-duty alternatives.

❓ Do you offer custom lengths for bulk orders?

Yes, we can manufacture custom lengths for container orders. Standard lengths range from 270mm to 550mm. Please specify your required length and volume when requesting a quote, and our engineering team will confirm feasibility.

❓ How does HONGYI quality compare to European brands like Blum?

We position ourselves as a high-value alternative. While we adhere to similar testing standards (50,000 cycles, 48h salt spray), our manufacturing efficiency allows us to offer competitive pricing. Many European furniture makers choose HONGYI for projects where Blum specifications are required but budget constraints exist. We recommend ordering samples to evaluate performance firsthand.
