Length:Choose 1870mm or 2100mm

2100mm: The faceplate has stamped on it SI 3/PZ GR4 ATL FFH 1880 - 2380
Locking Points: 2 rollers
Spindle to Key: 200mm the door handle and cylinder lock are 2 separate gear boxes from each other and allow the patio to be operated from inside and outside.
The faceplate has stamped on it SI 3/PZ GR4 ATL FFH 1650 - 2150 or 1880 - 2380 (This is the size range that the lock will cover. The measurement is taken from the top corner to bottom corner of the full length of the patio on the handle side)
Do not only measure the lock mechanism include the corner extensions that connect to it at the top & bottom. This is the FFH (full frame height sometimes called rebate height) Pick the mechanism that falls between these sizes.
The lock is then simply cut down to size with a hacksaw leaving enough connecting teeth underneath to link into the corner extensions.
Underneath the faceplate are teeth to connect to any corner drive gears.
This patio generally has handles to both the inside and outside faces of the door and has a seperate euro profile door cylinder lock to dead lock the patio doors (although some fabricators have been known not to use this and fit either a handle to the internal only or a blanking plate externally to cover the seperate cylinder lock)
