Low profile cockspur window handles for alu frames - do they exist?

[Bensonville]

Hello,

I need to replace the cockspur (non locking) handles on my old double-glaze aluminuim awning (outward opening) windows.

Reason being that I'm installing a blackout blind and there isn't enough clearance in the window recess with the current cockspur handles – they stick out too far into the recess as they're around 4.5cm in depth.

I've searched for quite some time now but can't seem to find any non-locking low profile or offset handles to replace them.

Does anyone know of any or can anyone think of an alternative closure mechanism to standard handles that would be more space saving and work with these old alu windows?

Thanks,
Ben
