CELT pear-shaped collar type 401/421 is used for cast-iron or PVC pipework on ceilings. The difference from a traditional pear collar is that the collar pipework can be installed in place (see video). Either by tilting the pipe and opening the collar, or by pulling the collar slide from the inside (into open position). Then simply clip the collar in position and tighten using the top nut. This support system enables the installer to work alone. The shape of our pipe hanger collar allows an important adjustment range for the slope and therefore retains its easy installation. Our suspension collar is available in 2 models: non-insulated (401) or isophonic (421), for pipes diameters from 2 to 17 . Most commonly used in basements of buildings in elevation, it may also be used for crawl spaces.
