The replacement spring mechanism you ordered for your 2022 Keystone Outback 328RL roller shade does not include the autostop mechanism. The autostop is essential to keep the shade in the desired open position and prevent it from retracting unintentionally. For your shade, the compatible autostop part is the Irvine .75" Auto Stop (SKU: MRL-A1800), which can be added to your order to resolve this issue. Before purchasing, verify the part visuals and descriptions to ensure compatibility. Additionally, installation videos are available online to assist with proper fitting. If you need further assistance or confirmation, contacting the manufacturer after their next business week is recommended.
