LONTAN 9 in Undermount Soft Close Drawer Slides - Full Extension

In this review the LONTAN 9 in undermount soft close drawer slides are evaluated for homeowners and cabinet makers who want quiet, full extension drawers with a hidden installation. The single biggest reason to buy is the combination of a concealed bottom-mount design with a hydraulic soft close mechanism, which delivers smooth, silent operation and full access to the drawer. The review focuses on real-world use, durability, and installation considerations so you can decide if this set of 6 pairs suits a kitchen, bathroom, or workshop project.

Key Features

• Soft close: The hydraulic damper provides a consistent soft close action that prevents slamming and extends drawer life.
• Full extension: Full extension travel gives easy access to the entire drawer box so items at the back are reachable without removing the drawer.
• Concealed undermount design: Hidden bottom-mount rails keep the furniture looking clean and high-end while improving safety by sitting under the drawer.
• Heavy-duty construction: Galvanized steel construction supports up to 100 lb per pair, making these suitable for heavy kitchen or utility drawers.
• Includes mounting kit: Each package contains rear mounting brackets for face-framed drawers, adjustable locking devices, screws, and instructions to simplify installation.
• After-sale support: The brand provides customer service for quality issues, which is helpful if parts need replacement or clarification.

Who It's For

These undermount slides are best for DIYers, cabinet makers, and renovators who want a concealed, professional-looking slide with reliable soft close and full extension. They are a practical choice for kitchen cabinets, bathroom vanities, or heavy utility drawers where a 100 lb load capacity is useful.

Those who should look elsewhere include buyers who require specialized lengths outside 9 in, or users who prefer side-mount hardware or an ultra-easy retrofit system for non-standard drawers. Installation can require attention to alignment, so complete beginners may prefer professional fitting.
