It seemed that assemblers and installers would welcome a simple click-fit and comprehensive program of enclosure/cabinet hardware, without all the fiddling about.
By connecting ideas in a new way, the engineering team developed a pioneering technology which it called DIRAK-SNAP-Technology (DST). The resulting system is said to offer easily-made high-strength panel connections without the use of any tools – so that specialist panel builders can create the perfect solution, simply and securely in seconds. It is a system which offers precise, quick installation with reduced assembly time and high-retention, safe, vibration-proof service, according to the supplier.
It adds that DIRAK-SNAP-Technology greatly reduces the risk of assembly errors, such as improper torque specs. An audible click confirms proper assembly, which is helpful especially in applications which are hard to access. Removal is with either standard or DIRAK-specific tools.
The design concept is based on the same principle as a slam-latch, similar to those used in a door.It is made up of two wedges with ramped edges, and a spring set into a window within the wedges. These components are then inserted into the hardware and secured with a plastic plug to keep them in place. As the DST component is pressed into the sheet metal cut-out, the ramps on the wedges allow them to retract against the spring. When the ramps pass their apex, the spring pressure spreads them back outwards, resulting in the distinctive ‘snap’ sound. The component is thereby secured into the sheet metal, resulting in a secure, high-strength connection which naturally tightens.
The DST series includes captive fasteners for light-weight sheet materials as well as for heavier gauge materials and heavier duty applications, for example enclosures and cabinets. Conceived as a complete system, components include: cam catch, clamping handle, clamping latch, compression latch, quarter turn locks, swinghandles, concealed hinges, removable pin hinges, external hinges for surface mounted doors, lift off hinges, adjustable hinge, bridge and bow handles, finger pull handles, slam latch, recessed pull handle, tubular handle, stainless steel hinges.
Many DST products are tested according to DIN EN 61373 for vibration and shock and GR-63-CORE, Issue 4 for earthquakes.
Reinforcement plates are available to increase strength and load capacity.
Where electrical continuity is required then safe and reliable electrical grounding is achieved with easily-fitted grounding clips. Where additional security is required then components requiring specialized DIRAK tools are available to address cases where vandalism or theft are concerns.
