SL-H1-3427-40 Constant torque hinge
The SL-H1-3427-40 is an aluminum alloy constant torque hinge with an anodized black finish: internal friction elements hold a table, lid or panel at any angle through its travel and prevent it from falling open, in a flush-mount body that occupies minimal installation space.
- SKU : SL-H1-3427-40
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. Match the black anodized finish to the panel
The aluminum alloy constant torque hinge comes in an anodized black finish for equipment where dark hardware blends with the enclosure styling.
2. Park the panel where the operator leaves it
Internal friction holds a table, lid, or panel at any angle through its travel without falling open.
3. Protect service safety on lids
Controlled friction replaces gas struts and prop rods, preventing slam during inspection and maintenance.
4. Verify the anodizing for the site
Confirm the anodized finish against salt-spray exposure where the equipment faces corrosive atmospheres.
5. Lock down torque values early
Friction elements are cycle-tested for stable torque; confirm torque values and installation dimensions per drawing.
