Saracen Gearbox C 
This brand new Saracen Gearbox is the ideal replacement for broken Saracen shootbolt locking mechanisms in UPVC windows, when used with two extension rods. It's a suitable replacement for the obsolete Saracen Eclipse gearbox.
 
Handing: 
Holding the gearbox in horizontal upright position, you'll notice an arrow on the little deadbolt. 
If the arrow is pointing right, the gearbox is Right Handed.
If the arrow is pointing left, the gearbox is Left Handed.
