Floor mounted soft-close drawer rails These underbody guides are designed for easy installation and smooth, quiet operation, reducing noise by up to 30 decibels. Unlike side mounted rails, floor rails eliminate side wobbling and provide a sturdy, visually appealing finish. Steel construction Made of cold rolled steel, these soft close drawer runners are strong enough to support up to 88 pounds. The galvanized coating prevents oxidation and rust, delivering long service life. Quiet and gentle closing Equipped with springs on both sides, these drawer guides offer a seamless, smooth closing experience. The built-in damping hydraulic cylinders feature 3D adjusters and metal plates for precise alignment on different cabinets. Three-tier full extension Designed for convenience, these drawer guides come in a three-piece design with full extension, allowing easy access to items without blind spots. Compared to two-piece designs, they offer improved functionality and ease of use. Use scenarios - Kitchen drawers with heavy pots and pans: enjoy quieter operation, improved stability, and full access to contents without side wobble. - Workshop or garage tool storage: sturdy support for heavier loads and precise alignment across different cabinet configurations. - Laundry or bathroom storage: soft close operation reduces noise and keeps items secure and organized in frequently opened drawers.
