Your tilt latch resembles our 26-333 Better-Bilt Window Latch pair. To confirm if this is the right replacement, carefully compare the dimensions shown on the diagram below. This part is only available in black.
To determine if the Series 600 spiral balance is what you have, you'll need to confirm the diameter of the metal tube. This should be 5/8", which may also appear to be around 1/2" (or 9/16"). There is a chance you could also have a 3/8" diameter and in that case, you'd need the Series 900.
You'll also need to confirm the length of the metal tube, not including the plastic tip. This will help determine the weight range your balance tubes can support. Although, it looks like you balance does not have a tip color. If it doesn't, you'll need to obtain the exact weight of the movable sash. Once you have the sash weight, you'll be able to select the tip color using the chart shown below the product description for the series and length of your balance.
These balances both use the 75-006 spiral balance charging tool.
In regard to the shoe, to confirm if you've chosen is the correct replacement, you'll need to compare the measurements shown on the diagram below. If they are not a match, please write out the measurements for your shoe. I'd be happy to search for a more accurate solution.
You'll need the S900-28 spiral balance with either the red tip (used on windows weighing 10 to 22lb) or the green tip (used on windows weighing 14 to 26lbs). They will both work well in the window.
