Adjustable & Soft-Close Damping Hinges

SL-H1-3426-30 Constant torque hinge

The SL-H1-3426-30 is a zinc alloy constant torque positioning hinge for light-duty lids and panels: it provides constant resistance across the entire range of motion, so the panel stays where the operator leaves it, mounted via internal threads for a clean exterior.

  • SKU : SL-H1-3426-30

Torque hinges use controlled friction to hold a door, lid, or panel at any angle without gas struts or prop rods, preventing slam and improving service safety. Friction elements are cycle-tested so torque stays stable over the service life; torque values and installation dimensions per drawing.

How To

  1. 1. Position light lids without hardware

    The zinc alloy constant torque positioning hinge gives light-duty lids and panels constant resistance across the entire range of motion.

  2. 2. Let the panel stay where placed

    The panel stays where the operator leaves it — no gas struts, stays, or extra hardware required.

  3. 3. Mount through internal threads

    Internal-thread mounting keeps the exterior clean on exposed installations.

  4. 4. Validate the zinc body for the environment

    Confirm the zinc alloy body against salt-spray exposure on industrial or outdoor equipment.

  5. 5. Keep torque stable through the life

    Friction elements are cycle-tested so torque stays stable over the service life.
