Altro Cast Bulb End Mortice & Hook Plate Casement Window Fastener - Reversible - Polished Brass

Window furniture

For the price the fasteners are fine. My only concern was how much distance there is between the underside of the plate of the fastener to the blade that engages in the hook or mortice plate. I had to house the fastener into the casement due to moulds on the mullion of the window which would’ve been cut to receive the mortice plate if I hadn’t. I only just managed to get them to work within the dimensions of the windows sections.
