Main specifications
General information

Material

High-resilience polyamide based (PA) technopolymer, black colour, matte finish.

Rotating pin

AISI 303 stainless steel.

Standard executions

CFA-F-B: nickel-plated brass bosses with threaded hole.
CFA-F-CH: pass-through holes for cylindrical head screws.
CFA-F-SH: pass-through holes for countersunk head screws.

Features and applications

CFA-F hinges are recommended when the opening of the door must not exceed the limit of 95°.

Once the hinge is fitted onto the machine/door, the teeth of the detent system remain inside the hinge. Thus the operator cannot reach them for the safety of his hands.

Rotation angle (approximate value)

Max 105° (-10° and +95° being 0° the condition where the two interconnected surfaces are on the same plane).

To choose the convenient type and the right number of hinges for your application, see the Guidelines.
