Product review (5 stars): Great piece of equipment!
Our laundry room has a cabinet in it with an opening that is perpendicular to the front of the washer and drier. To open the door of the cabinet, the drier has to be back in very close to the wall. When we moved into our home, the drier vent was one of those flexible metal ones, which was taking up probably about a foot of space, making it impossible to open the cabinet door--which was not the end of the world, but still all things considered it is nice to have the extra space to store rags and cleaning supplies and what have you. Bought this adjustable periscope online and, even though I am the furthest thing from a handyman, got it installed fairly easily and can now open the cabinet; clearance from wall to back of machine is now about six inches. I looked at these at Home Depot and Lowe's but the ones they sold only adjusted to 12 inches, as I recall, and I needed more room than that because the drier exhaust is on the back left side of the drier, but the exhaust going out of the house is on the right side, so I needed plenty of room to bridge that distance.
