<p>#CMT# #/CMT# The fastener protrusions (4) on the box frame (1) are joined via a resilient bellows-like section (8) to either an intermediate part (6) connecting the protrusions to each other, or to the frame base. This section allows the protrusions to move in an axial direction relative to the frame, whilst the intermediate part or frame base has a fixed position in relation to the frame. #CMT# : #/CMT# The box comprises a frame and a fastener means (2, 3) for securing the box to a construction panel. This means comprises a fastener flange (5) protruding from the mouth of the frame, and fastener protrusions provided on opposite sides of the frame. The protrusions can be pressed into the mounting opening in the panel so that they engage with the rear side of the panel. Clamping screws are used to move the protrusions towards the flange. #CMT#USE : #/CMT# For installing electrical cables in a building. #CMT#ADVANTAGE : #/CMT# The box can be easily and firmly secured inside openings in different thickness construction panels. #CMT#DESCRIPTION OF DRAWINGS : #/CMT# The figure shows an exploded view of the connection box. 1 : box frame 2, 3 : U-shaped pieces 4 : fastener protrusion 5 : fastener flange 6 : intermediate part 8 : resilient bellows-like intermediate section.</p> |
