2-Pack 90/180 Degree Hidden Folding Shelf Hinges – Heavy-Duty Sprung Bracket Holder for Convertible Furniture

Maximize floor space and create versatile convertible furniture with this 2-Pack 90/180 Degree Hidden Folding Shelf Hinges. Designed for drop-leaf dining tables, folding desks, kitchen extensions, cabinet doors, and hidden wall shelves, these heavy-duty steel hinges feature a dual-position locking mechanism that holds surfaces firmly at either 90 degrees or 180 degrees flat. Constructed from cold-rolled steel and plated with a zinc-coated anti-corrosion finish, they deliver high load-bearing capacity and long-term resistance against rust, bending, and mechanical wear. Built-in high-tensile spring mechanisms ensure smooth, controlled opening and closing without sudden drops, while the concealed low-profile bracket hides neatly between wood panels for a flush, professional finish.

Key Features

• Dual 90° & 180° Position Locking: Seamlessly locks into a 90-degree right angle or unfolds to a flat 180-degree position for multi-functional space saving.

• Heavy-Duty Cold-Rolled Steel Build: High-tensile steel construction supports heavy loads without warping, sagging, or joint loosening.

• Smooth Sprung Assist Mechanism: Integrated internal springs cushion movement, providing controlled folding and unfolding transitions.

• Concealed Flush Mount Profile: Hidden bracket design tucks neatly into joint gaps, keeping mounting hardware out of sight when open or closed.

• Anti-Corrosion Zinc Plating: Galvanized surface finish protects against moisture, rust, oxidation, and friction wear over time.

• Pre-Drilled Precision Screw Holes: Features multiple counter-sunk mounting points for fast, secure installation onto wood, MDF, and plywood panels.
