Acetal based (POM) technopolymer. Flammability class UL94-HB. Black colour, matte finish.
Polycarbonate based (PC) technopolymer, black colour, matte finish. Flammability class UL94-V2.
AISI 304 stainless steel screw.
AISI 303 stainless steel adjusting boss.
Assembly by means of pass-through holes for cylindrical head screws.
The main feature of CFU. hinge is the possibility to adjust the resistant torque of the door on which it is assembled, facilitating the door clamping in the various positions of opening, partial opening and closing.
To adjust the friction force, simply turn the screw on the hinge body, clockwise to increase the friction and anti-clockwise to reduce it.
Max 275º (-95° and +180° being 0° the condition where the two interconnected surfaces are on the same plane).
Do not exceed the rotation angle limit so as not to prejudice the hinge mechanical performance.
The resistant torque values of 1.4 and 4 Nm can be obtained by applying a maximum tightening torque of 0.8 Nm (CFU.40) and 4 Nm (CFU.60) on the adjusting screw.
The hinge had been tested with more than 60.000 opening and closing cycles and the values of the resistant torque was unchanged.
To choose the convenient type and the right number of hinges for your application, see the Guidelines.
