- Y Bore for door lock
- Do not grip bonding surface.
- It is not the length of pressing in time but rather the level of pressing (approx. 10... 15 N/cm2 ) which is decisive here.
- Separation of seal after pressing destroys the adhesive layer.
Suspend seal (1) with open lip pointing inwards over door. Pull protection of positioning aid (liner) off seal in sections.
Stick on seal (1) as follows:
- Position seal with color coding on door window frame at rear top.
- Gently press seal without stretching up to start of positioning aids.
- Check positioning of seal, correct if necessary (sag max.3o mm).
