The 28D is Swisco's 2840, and measures 29" in length. You will want to try and match the top and bottom fittings of the current balance to the replacement options we carry online.

Looks like SWISCO balance series 380. The 29" length balance with 28D normally translates to 2840, to check, remove the window sash and place it on a scale. S380-29 with stamp number 2840 will carry a window sash weight range of 23 through 28 pounds.
Suggested sash weights do not include the manufacturer's sash friction due to manufacturing methods and weatherstrip types.
