1 Observing the A, B and C positions shown in Figure 8, mark the 2 fas-
tening points for the guide's front bracket in the centre of the garage door
(or slightly off-centre – Figure 11).
Depending on the type of material, the front bracket can be fastened
using rivets, anchors or screws (Figure 26). If positions A, B, and C (figure
8) allow it, the bracket can be fastened directly to the ceiling.

lift the guide from the front and secure it with two screws, anchors or riv-
