Comes with a window spacer unit with accordian blinds on each side. Very little use from our former home. 6000 BTUs. Can be tested for you when you come. Located in Deep Cove area. No long holds. **To the person who emailed from a Shaw address asking about the window spacer kit - I could not reply to your address as it stated "address not found", so please send a phone number if you try to reply to this ad again. Thanks
