hi, i need 6 repolacement parts of the type in the enclosed image. any chance you might carry these parts. i think the name of this part is a window sash balance lock. i ordered 2230 window balances from ya'll before discovering that the balances do not work without these little parts.

Start by looking at our 18-009 and see how well its dimensions line up to your own. If they differ in any way, let me know exactly how and we can find something better.
