Is it just the plastic sliding bit you're after? I've got a pair in the shed as I took mine off for my new door cards.
yes and the black trim, that was going to be my next question, I have new cards, should I use the vents or just ignore them and blank them off? thank you
Don't blank them off. They help ventilate the inside of the door and aid drying out any sitting water that hasn't drained out of the drain holes.
