The traditional lock unit of these System Knee Joints is determined by the
centrically fabricated 17Y41 Lock Hammer (4) and the centrically fabricated
30U45 Lower Joint Section (2). The 17Y41 Lock Hammers are connected
by the 17Y30 Lock Bale.

INFORMATION
The Ottobock System Joints are exposed to higher structural loading
due to various clinical parameters, such as forefoot lever length or the
angle of the orthosis.
Insert the 17B38, 17B39, 17B40, 17B41, 17B84 17B85 System Side Bars
or the 17Y105, 17Y107 System Lamination Bars as connection elements
into the Knee Joint Connection Channels.
After adapting the system splint on the system connection plugs, the side
bar sets must be bonded into the connection plugs of the system joints
using 636W28 Ottobock Special Adhesive for reasons of stability. To do
so, degrease the surfaces to be glued with 634A1 Ottobock Thinner and
Solvent, thoroughly mix the contents of the two tubes of special adhesive
and hardener and apply the mixture into the connection plugs. Insert
the side bar and screw it into place using 501T7=7.5x9xM5 Oval Head
Screws. The adhesive takes 3 to 4 hours to set. Final bonding strength will
be reached after 16 hours.
The Ottobock System Joints and System Bars and System Joints are made
of steel that is both rust-resistant and acid-resistant. We recommend final
