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. 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. Let the panel stay where placed
The panel stays where the operator leaves it — no gas struts, stays, or extra hardware required.
3. Mount through internal threads
Internal-thread mounting keeps the exterior clean on exposed installations.
4. Validate the zinc body for the environment
Confirm the zinc alloy body against salt-spray exposure on industrial or outdoor equipment.
5. Keep torque stable through the life
Friction elements are cycle-tested so torque stays stable over the service life.
