REHAU BENCH TRUNKING
INSTALLATION GUIDELINES



Cabling inside this trunking must only be installed and maintained      2. Fixing the Base
by a competent person in accordance with BS7671 (UK Wiring
Regulations)                                                            Base must be fixed to worktop and back wall (if available) 25mm from
                                                                        the ends as shown below.
PROFILA Bench Trunking is a cable management system intended
for distribution of low voltage power and communication circuits on
worktops.

1. Generalities

PROFILA Bench Trunking is a cable management system based on
an asymmetric triangular shaped profile for protecting low voltage
electrical and data installations.

Due to its asymmetric design the system can be installed in two
different configurations:




                                                                        Fig 3: Fixing distances


                                                                        Fixing pints between end cuts can be done alternating along the

                                                                        head screws and washers.
Fig 1: High configuration            Fig 2: Low configuration



High configuration - Default configuration for all fabricated
                     accessories, recommended in most applications

Low configuration - It requires special internal and external corners



        PROFILA Bench Trunking can be used in continuous extrusion
lengths or as individually assembled POD units.

        Internal and external corners come in high configuration as
standard. Low configuration corners must be ordered specifiying this    Fig 4: Interval distances

requirement.
                                                                                If worktop and wall are not perpendicular (90° angle), fix base
                                                                        only to worktop.
2.1. Fixing Adjacent Lengths of PROFILA Bench Trunking                      3 Protective Foil

Adjacent lengths of base must be aligned and joined together by using       PROFILA Bench Trunking profiles come with a protective tape to
3 off metallic dowel pins (Art.265921). Some pins are supplied with         prevent damage during transport and installation. This protective layer
