Nico Espag Lock Description
The Nico Espagnolette (Espag) is a simple way to provide secure multi-point locking for windows. The espagnolette bolt is strong and reliable with proven long-life performance. All Nico espagnolette locks are tested in the Nico Test Centre over a 30,000 duty cycle. They are also treated with a super coat 500 finish, which gives it a 480hr salt spray reading
The Nico window espag locks are the closest direct replacement lock for the old mila gr window locks. The positions of the roller cams and screw holes are the same for the gr40, gr60 and gr80. The center roller cam on the gr100 is located exactly in the middle of the lock. This is the only difference. You will just have to reposition the keeps on the frame to suit the new position of the roller locks.
Old Mila GR Lock Size Guide
On the old Mila window lock there will be a code stamped along the faceplate of the lock. The code will be GR and a number (eg. GR100). This is the code for the length of the lock.
- GR40 (350mm long) – for a sash between (400mm – 550mm) – 2 rollers cams
- GR60 (550mm long) – for a sash between (600mm – 750mm) – 2 roller cams
- GR80 (750mm long)– for a sash between (800mm – 950mm) – 2 roller cams
- GR100 (950mm long) – for a sash between (1000mm – 1150mm) – 3 roller cams
Next check the backset of the lock. Get a measuring tape and measure from the edge of the faceplate to the centre of the handle. The most common sizes will be 20mm or 22mm. Alternatively, you can remove the lock from the window. On the lockcase of the lock the size will usually be stamped. Eg. 22. Note: If your backset measures 19mm, please choose 20mm.
