In comparison with simple quarter-turn locks, swinghandles offer a much higher torque capability than standard quarter-turn latches; consequently greater closing force is available. This is important for enclosures with thick gaskets or for larger doors with rod latches where multi-point closure is employed for greater sealing or security.
With DIRAK swinghandles, access control to server racks can be professionally managed and alongside conventional swinghandles, FDB offer safety-tested variants of the swinghandle range, for example with one locking cylinder or with two tandem-locking cylinders.
As special equipment, FDB offer swinghandles with mechatronically secured latches, locking cylinder or actuator, and also flush-mounted and standard raised handle variants. Some designs feature tool-free installation, with versions in zinc die-cast, polyamide or stainless steel.
Design styles include low profile, Trimline, vandal-resistant, dual key security or padlockable; a swinghandle with LED status indicator is also offered.
Sealing performance is to IP65 in black. Other features available include chrome-plated or stainless steel with profile cylinder, key cylinder, combination lock, square threaded rod actuation and KABA cylinder.
