2-Piece 80-Degree Spring Hinges Set – Cabinet Door Foldable Lifting Brackets & Sofa Sprung Lifters

Maximize your home storage and enjoy smooth, effortless lifting with this 2-Piece 80-Degree Spring Hinges Set. Specially engineered for top-opening cabinet doors, storage benches, foldable bed frames, and sofa storage compartments, these heavy-duty lift brackets provide reliable support when opening and closing heavy lids. Forged from high-tensile cold-rolled steel, each pair features high-tension coil springs that counterbalance weight, holding lids securely open at an 80-degree angle for easy hands-free access. The durable zinc-plated surface finish guards against rust, oxidation, and friction wear, ensuring smooth operation over thousands of lift cycles. Whether you are building custom flip-up kitchen cabinets or repairing a storage ottoman, these spring lifters provide structural reinforcement and seamless movement.

• Rust & Corrosion Protection: Durable zinc-plated coating protects metal components against humidity, tarnish, and wear in kitchens or storage units.

This 2-piece 80-degree spring hinge set combines high-tension spring counterbalancing, heavy-duty cold-rolled steel strength, and smooth pivot action—giving your flip-up kitchen cabinets, storage ottomans, sofa beds, and custom furniture an instant commercial-grade upgrade.
