Spring hinges

These self-closing hinges automatically facilitate the closure of door wings after opening, and their innovative design with patented torsion spring operation has earned international acclaim. What sets Justor apart from the competition is its use of robust torsion springs and steel sheet encasement, delivering unparalleled value and an uncompromising visual appeal.

Crafted to ensure a smooth automatic closure for various door types, the Justor self-closing hinges employ sets of steel blades operating in torsion, known as torsion springs. Their superior production quality and robust materials guarantee high resistance against breakage, deformation, and maximum elasticity, setting them apart from similar products.

These hinges boast a lifecycle of up to 500,000 cycles. Justor’s self-closing hinges are available in anodised aluminium for internal doors and stainless steel for external doors, making them suitable for various applications, including hotels, restaurants, hospitals, factories, and laboratories.

Single-action Hinges (ST and SA)

Ideal for automatic closure when installing a hydraulic door closer isn’t feasible, single-direction spring hinges offer adjustable closing speeds without the need to remove the door during installation or afterwards. The ST 150 model doesn’t require door frame preparation, while models SA 120 and SA 180 need prior door frame processing.

Double-action Hinges (DA)

Two-way spring hinges, or “cowboy” hinges, are versatile and commonly used in various door types. The closing strength is adjustable, and the new DA120W and DA180W models offer a hassle-free installation without door frame preparation, fitting smoothly into any environment.

Correct hinge installation involves placing hinges strategically on the door edges, ensuring proper functionality. Justor hinges are available in various finishes and material grades to complement different projects. The door size directly impacts the hinge selection, and our team can assist in choosing the ideal product for your project.
