Locking options for minimal windows

Minimal locks for sliding doors

The minimum window sliding glass door system is characterised by its minimal aesthetic maximising the glass within an opening and hiding as much of the frame away as possible. The same approach is applied to all locking options for the colour minimal windows. 

Each locking option available – whether you opt for an internal thrust lever handle and integrated key electrical locking or the new hidden handle – are all designed with security and minimalism at their heart. 

Every looking option for the sliding glass doors are integrated fully into the frame. No bolt-ons, no additional structures. The locking profiles are integrated into the slim sightlines of the sliding glass doors to ensure inherent security. 

With the entire minimal windows sliding door range there are a wide variety of locking options possible to ensure your sliding glass door fits the building specification and use. 

Manual Internal Lock for Sliding Doors

The most common and widely used of the locking options for the Keller minimal windows is the internal thrust lever locking option. This is referred to as the type 2 lock and is operated manually and only from the inside of a building. 

The locking handle is built into the interlock of the sliding glass door. Within the vertical profile are steel shoot bolts and when the handle is turned these shoot bolts fit from within the profile into precast holes within the ceiling and the floor. 

This manual locking option for sliding doors is typically located at the leading edge of a glass door configuration however, alternatives are possible depending on the design requirements. The location and height of the handle can be designed at any height on the interlock although 1.1m from FFL is used as standard.   

There are also various options for the design of the thrust lever handle including the shape colour and material. Finishes off the handle can be chosen to complement or contrast with the sliding glass door frame.  

Locking for Bi-Parting sliding doors

When the minimal windows are bi-parting, a range of locking options are possible including all of the options on this page.  

When specifying a bi parting glass door with the continued minimal sight line at the centre, a four-point locking box can be used. When the thrust lever handles are engaged as above shoot bolts fit into the ceiling and the floor as well as the other direction of glass doors. This allows you to lock the bi parting glass doors from one location at one time.  

Key locking for sliding glass doors

A removable key lock is a possibility with all minimal windows installations. 

For an internal key lock, the thrust lever handle (as detailed above) is replaced with a removable euro cylinder key. The locking point is located within the vertical profile and when the key is turned it activates the integrated steel shoot bolts locking them into place in the ceiling and the floor. 

This locking option is part of these certification for the PAS:24 security 

External key locking is also possible which can be a useful option for pocket doors or sliding doors which are the only access to a space. Here, the key lock can be mounted on the wall structure. When the key is turned hooks or activated within the vertical fixed frame which hook into the sliding door frame locking it securely into place. 

Electromagnetic Locking for Sliding Doors

Remove all need for keys or manual operation with an integrated electromagnetic lock for the minimal windows.  

If you’ve specified automation for your sliding glass doors the electromagnetic lock is used to standard. However, an electromagnetic lock is still an option for manually operated doors.  

The electromagnetic locks sits within the head frame of the sliding glass doors and can be activated through any electrical means. Whether you integrate the locking option into a smart home automation system, an app or have a simple switch on the wall, the electromagnetic lock is a secure and highly minimal way to lock your sliding glass doors.  

An electromagnetic lock might also be a suitable locking option for minimal windows that need to be locked and unlocked from the outside.  

Soft Open/Close

The NextGeneration Slider is designed with a unique locking option called the soft open-close. This glass door locking option is suitable for the hidden handled design detail. The leading edge of the sliding glass door is fully recessed into the frame and building finishes leaving a wall-to-wall glass design. To open the door, you press a small button in the wall which unlocks the electromagnetic lock and slides the glass door slightly out of the wall opening. This then allows you to grab the sliding door and operate it manually as normal. 


When closing the sliding door, you push the door closed manually. When the door is close enough to the wall frame, the switch will activate allowing you to press the button which softly pulls the sliding door into the wall and locks it into place.  

The hidden handle and soft open-close locking option is only possible with the NextGeneration Slider.
