•
Integral nylon spring eases the cable
into a lazy bend;
prevents kinking and
assures longest cable and product life.
•
Designed to pass CSA’s 50,000 cycle
vacuum cleaner test ( C22.2 No. 67)
and UL’s 859 specification for
Household Electric Personal
Grooming Appliances Cord
Flexing Test.
•
Assembly friendly! Independent of
insertion into the panel, RDD Lockit
™
Strain Reliefs self-lock onto the cable.
Preassemble RDD Lockits off line
for final assembly at a later time
or remote location, for lower
installed cost!
•
Install easily with fingertip pressure
into a standard round or Double D
hole. No tools required, even for
hand assembly.
•
Protect the lifeline of your electric/
electronic products by absorbing the
forces of push and pull that may be
exerted on the flexible power cord.
Double D design eliminates the
possibility of part rotation under forces
of twist.
•
Multiple panel locking steps secure
Lockit Strain Reliefs into a wide range
of panel thicknesses for a
flush,
finished fit.
•
Heyco’s automated Pre-Assembly
Equipment speeds assembly of the
RDD onto the cable and thus lowers
costs while greatly reducing risk of
carpal tunnel syndrome.
See pages 4-15 & 4-16.
•
See page 4-38 for corresponding
Mounting Hole Plugs
which can be
used to fill blank/unused Mounting
Holes and thus allow for a single panel
design for multiple applications.
