The fitting work is essentially determined by:

• the arrangement of the screw mounting and locating surfaces for the guideways and carriages
• the accessibility of the fixing screws.

The fitting work can be evaluated according to the scheme, Figure 1.

The structure is ascending and describes the work according to the following criteria:

• simple fitting without fitting aids 
• simple fitting with fitting aids 
• demanding, time-consuming fitting with fitting aids .

For reasons of time and cost (reduced fitting work) only variants corresponding to and should be selected.

For assessment of fitting work see table.

The following table shows the fitting work as a function of the adjacent construction.

The tables show different alignment methods for guideways.

If the guidance system is in a suspended arrangement, a drop guard  is recommended, Figure 2.
