GU 4 Roller UPVC Door Lock

For basic multipoint locking of a uPVC door, this is GU's 4-roller lock setup, which grants four locking points (plus the central latch & deadbolt) in form of roller cams. 

In this day and age, most doors are fitted with a multipoint locking solution offering something more substantial than rollers alone.  A typical setup now is hookbolts, rollers and the central latch and deadbolt.  However, if you need to replace like-for-like on an existing broken or worn out lock, then this may be the solution for you.

If this is the type of lock you're looking for though, we have all the backset sizes originally available for this series, there's a 28mm backset model for narrow stile and glass panel uPVC doors, the 35mm backset model which is the most common size, and then 40mm and 45mm backset sizes for the wider or more inset door setups where this larger size is more appropriate.

The PZ centres are still 92mm on these too, which allows for a no-fuss retrofit with the majority of installations.
