Hehr Jalousie D-Seal
This D-seal was used as both the top and bottom seals on Series 1600 Hehr Jalousie Windows in the 1950s and 1960s.
Note: There were two different top and bottom seals used on Series 1600 windows, the wedge-seal and the D-seal. The two seals are not interchangeable. The wedge-seal requires the larger channel opening. The D-seal will fit into either channel but the wedge-seal will only fit into the window with the larger channel opening. For the wedge-seal, see our part #70-3841-254.
