I'm looking to replace a right hand dual operator and crank for my 33" x 33" kitchen window. The only indetifiers present are the brand: Crestline (located on the front of the operator cover) and the sequience: 20810 and the text Entry Gard truth (located on the dual hinge mechinism). I have provided pictures of the window parts. Do you have a replacement part to get the window back in working order? Thank you, Leanne

Thanks for posting. This looks like the 39-031 and 38-032 Dual-Arm Operators. Just make sure the arm(s) match what we show below. For new covers and handles, see the 39-114L and 39-107. For the Sash Lock, see the 38-075. See if it matches up. See the 38-089 Keeper.
