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.
•
Consult Heyco for other wire types
and sizes.
•
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.
•
For Double D Mounting Hole Punches,
