The fully welded four sided design also ensures the opening is totally square at a 90° angle.
Our closers are available in standard off the shelf brick opening sizes.
This ensures that when you come to install your windows they fit effortlessly using the simple click fit and screw system.
Becuase the closers always keep the correct shape and size, theres no need for excessive amounts of silicone or expanding foam to fill in huge gaps between the brickwork and frame.
