Screw protects hazardous areas from accidental entry
The Sentinel ratchet-action captive screw from Southco Inc. is
UL-recognized and meets both UL 1950 and EN 60950 specifications for
'service access'. Both specifications require restricted access to any
area of electronic equipment or machinery where a hazardous condition
exists. To help protect hazardous areas from accidental or unauthorized
entry, the standards require a 'tool-removable' door or cover. To meet
these standards, the Sentinel screw is tightened by hand, but if a
technician tries to loosen the screw by hand, the head merely ratchets in
the opposite direction without disengaging. Captive to the panel, fully
retractable, and spring-ejected, the screw is offered in slotted, Phillips,
or six-lobed-head styles.
'This product represents good engineering work', says contest judge
Altamuro. 'It includes many of the factors that a product should have to
be deemed as an excellent design.'
