Brand: Sichern
Sichern 5 Lever BS
Red case with rough finish.
5G curtain wheel.
Hard plate is in a straight line roughly 2mm up from the top of the curtain wheel.
When in the locked position the curtain will not back turn.
Use a 5 Gauge tension tool. Shallow anti-picks, very easy.
These measurements will also work for the sash lock version.
Drill to pick:
Measure 17mm up from the top of the key way then 15mm towards bolt.
Use a 6mm hard-plate drill bit followed by a flat ended drill bit to completely open up the hole without damaging the levers.
Drill for the stump (the last resort):
Measure 17mm up from the top of the keyway then 18mm towards bolt. Consecutive holes may need to be drilled to remove the stump. Use a 6mm hard-plate drill bit.
