Based on your description, it is likely that the spring mechanism in your Irvine Slow-Rise Day/Night roller shades needs to be replaced, especially if the shades won’t stay up or retract properly after being jarred. Elkhart RV Parts offers replacement springs in three sizes: 3/4", 1", and 1 1/4" wide. To select the correct spring, measure the width of the roller, not the spring itself. If you have the original brackets and clips, you may only need the spring; however, replacement clips and end brackets are also available if damaged. For installation or sizing assistance, feel free to contact Elkhart RV Parts. Replacing the spring is the most effective solution to restore smooth operation of your shades after impact damage.
