These arrived promptly and were well made, but they did not fit my windows. The locating lugs were slightly too wide. I “modified” them to get the wedge to fit but my wedges had a corner chamfer at the top of the wedge to assist the handle to ride onto the wedge – the handle jammed on these wedges. I knew the shape was wrong before I ordered them but they were relatively inexpensive so it was worth a try. Even when I forced the handle onto these I STILL had a draught (despite new max height DG Supplyline gaskets) because the side of one of my PVC windows was not flat but bowed. So, could not use them but great to see DG Supplyline stocking such a large range of window bits.
