Cross-link connectors are designed to connect the two 
longitudinal rods. 

1. Assemble cross-link connectors

Outside the operating field, push the appropriate length 
of cross-link rod Ø 3.5 mm through the two cross-link 
clamps (1). One right and one left clamp (1a) or two 
identical clamps (1b) can be used depending on the 
space available in each case. 

Alternative

If the distance between the two rods to be connected is 
less than 30 mm, one of the two cross-link clamps must 
be replaced by a cross-link clamp with rod (1c). Push the 
rod of the cross-link clamp with rod through the second 
cross-link clamp.

Do not tighten the set screws.

2. Mount cross-link connector

Click the assembled cross-link connector onto the rods  
Ø 5.0 mm (2a), ensuring that the set screws are com-
pletely unscrewed.

The cross-link rod Ø 3.5 mm can be angled by up to 
±15° (2b).
