Soft close dampening lift-off hinges: soft-close damper keeps lid from slamming shut.
Sold in pairs (type 1 and type 2).
Lift-off hinge type 1 has a grey shaft and the damper working direction is clockwise.
Lift-off hinge type 2 has a white shaft and the damper working direction is counter-clockwise (shown on the drawing).
Operating angle: 115°.
If the opening angle is wider than 115° (+/5°), mechanism is broken and damper doesn’t work any longer.
Provide a door stopper to prevent from overturning beyond the prescribed angle range.
Do not force the door to close faster in damper effective direction. It can cause damage to the product.
When the door opening angle is small, the dampers may not work smoothly.
Torque moment (pair):
• 3 to 5 N.m for part number 12-7-4280.
• 5 to 7 N.m for part number 12-7-4241.
Torque calculation:
Torque (N.m) = L (m) x 1/2 x W (kg) x 9.8 with:
• L = door height in metre.
• W = door weight in kilo.
Operating temperature: 0 to +40°C.
