Vital security feature on safety catch
Protex Fasteners has just launched the model 39-1260, a fastener with tool-operated safety catch, importantly requiring a "deliberate act" to operate it.
Protex Fasteners has just launched the model 39-1260, a fastener with tool-operated safety catch, importantly requiring a "deliberate act" to operate it Here a tool-operated safety catch means a slotted safety catch on top of the fastener that cannot be opened in the absence of an appropriate tool, and, in particular, cannot be operated simply by use of one's fingers

That vital security feature dramatically reduces the possibility of impulsive or accidental use, possibly during production or plant maintenance routines.
Also, the "deliberate act" has implications, for example, where fasteners on guards shielding dangerous machines or processes cannot in any way be released inadvertently, and therefore factory management may be absolved of liability for lack of care should staff injury result.
Recent Health and Safety At Work (HSAW) and CE Marking legislation addresses the issue of a "deliberate act".

Quick-action fastener meets SVA safety specs
Sports car builder selects quick-release, over- centre catches that provide high strength, flush panel fitment without any protrusions from the bodywork.
The model 39-1260, called the TooLatch, is a rigid, medium-duty, overcentre fastener with narrow base, manufactured by Protex in a choice of stainless or zinc-plated steel.
The product is 113mm long, weighs only 115g and yet has an impressive breaking strength of 494 kgf (4.84 kN).
Its steel loop will engage onto any one of six catchplates, whichever best suits the space and application.
Rigid Protex fasteners should be mounted on surfaces embodying some resilience, such as on GRP covers or to compress a rubber seal.
The TooLatch is designed to be opened by the thin edge of a flat-head screwdriver, metal tag, knife, steel rule or coin.
Another significant feature of the device is that its sprung catch mechanism engages automatically, allowing it to be rapidly snapped or slammed shut without using the tool: this reduces the timespan during which dangerous equipment may be left exposed.
Being in a family with the other rigid, medium-duty, fasteners of the Protex 1260 range, the TooLatch can be installed at critical locations among those more conventional types using identical catchplates.
With its slotted mechanism on the top face and having a low profile and narrow base, the new Protex TooLatch is also ideal for mounting in a recess where a relatively flush surface may be required and unwanted projections could lead to people tripping or clothes snagging.
In zinc-plated mild steel, the TooLatch suits a host of everyday industrial and agricultural uses such as covers, casings, guards and access panels.
A typical scenario is an access hatch above a roll feed press, where a maintenance engineer needs protection from the hazardous mechanical workings beneath.
In stainless steel, the TooLatch provides greater corrosion resistance for aggressive environments, say in process, power and marine engineering.
They may include sites where chemicals, pharmaceuticals, polymers, coatings, or food and drink are manufactured or packaged, or, likewise, areas of ships and docks where salt water and harbour pollution will corrode metals fast.
To aid productivity and accuracy in design and draughting, an AutoCAD drawing of model 39-1260, the TooLatch, is downloadable from the Protex Website www.protex.com now.
Independent British company Protex Fasteners produces the World's largest catalogue range of more than 600 lever-action, overcentre fasteners (or draw latches) and sells them direct from stock to hundreds of industries in over 50 countries.
