Sirs/Ms;
I am in need of some slide locks for vertical casement windows. It is a total of 50 7/8 inches long. It has "locking buttons" that are 3/8 of an inch in diameter and stand out 1/4 inch. They are placed, from the top, at 3.75", 19.125", 34.5", 44.375", and 50". The bar itself is .5" x .125". The bar is held by seven plastic guides which are in turn arranged to the frame.
I have attached four pictures of one such slide that I hope will allow you to see.
I do not know the original maker.
I believe I need four of these.
Thank you for your help.
David
