The modules accommodate hoses from 0.17 to 0.55" (4.3 - 14 mm). 3 x 0.17" (4.3 mm) hoses can be inserted on top of each other in the CFS 4.3 module, while 2 hoses can be installed directly on top of one another using the CFS 6 module. Each module is 1.08" (27.5 mm) wide and is inserted into the base plate, before being fastened in place with M4 countersunk-head screws. The exception is the CFS 55.9 module, which allows 5 x 0.35 (9mm) hoses with twice the width. The base plate and cover plate are available in widths from 2.95 to 9.45 (75- 240 mm). The height of the modules and spacers are 0.63(16 mm). Several layers can be installed directly above one another.
