Thank you. I need six (6) of these aluminum window black vinyl caps that engage the balances that support the window. The pictures sent are representative of the style,with 4 prepunched" holes from the mounting screws. These are single hung aluminum windows.

Start by looking at our 18-019. This is a similar kind of "double" top sash guide, though I don't know if our dimensions match yours. Look over our measurements and see how well they compare.
