Special features:
item products are based on different modular dimensions and their associated system grooves. Profiles from Lines 5, 6, 8, 10 and 12 each need corresponding sizes of fasteners. The profiles in Line X feature a Line 8 system groove but have a particularly flat surface with minimum curve radii that make them ideal for building sealed constructions.
Components that are RoHS-compliant contain no dangerous substances such as lead or cadmium. EC Directive 2002/95/EC (RoHS 1) restricts the use of certain substances in electronic devices and components. These include batteries, etc.
All substances are registered according to the REACH regulation. REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) ensures that users have accurate information on the type and properties of operating materials, lubricants, etc. that they might come into contact with.

Notes on Use and Installation
Chain Reverse Units 8 80 are used for reversing, clamping and driving Chain ½".
They are screwed into the end faces of Profiles 8 at a height of 80 mm.
It is possible to fit motors and couplings D55 directly to the Chain Reverse Unit.
The Chain Reverse Unit incorporates integrated chain tensioning block and clamp.
The Chain tensioning distance is 2x13 mm in total. The Chain tension must be set so that the Chain can also be operated with the slack side of the Chain only slightly pre-tensioned.
The Chain can be driven directly using the Chain Reverse Units or the Chain Counter-Reverse Unit. The sprocket wheels of the Chain Reverse Units are available with multi-spline hub VK14 or with a bore that can be machined as required. Use of multi-spline hub VK14 enables the modular accessories (Synchroniser Shafts) to be used without any restrictions.
The Chain Reverse Units are screw-connected into the core bores in the end faces of the frame profiles.
The Chain Guide Profile must be cut 50 mm longer than the aluminium profile, since it must project 25 mm into the Reverse Unit at each end.
