Areas of use:
To
eliminate the accurate length cutting of ducts which the ordinary NPU
connector sometimes requires when joining SR ducts. In this case the
slide-in coupling shall be secured with screws or pop rivets.
To
make it possible to use a duct that is cut to a too short length –
instead of having to cut a new duct to the correct length. In this case
the slide-in coupling shall be secured with screws or pop rivets.
To
assist when joining two ducts which run towards each other. E.g. when
building a system from two opposing directions. In this case the
slide-in coupling shall be secured with screws or pop rivets.
To
assist when inserting or adding an other product into an existing
system. E.g. the addition of a new piece of duct to replace a damaged
part. In this case the slide-in coupling shall be secured with screws or
pop rivets.
To facilitate access when inspecting and/or
cleaning a system – by simply sliding the coupling. The coupling acts as
an access cap. Lindab do not recommend this use of larger dimensions
than Ø315.
No Click function – has closed turned-over ends (at both ends).
