This is a shelf-equipped exhaust vent cover that I've used at home for several years. It's convenient for preventing the exhaust vent from getting dirty. As it has a shelf, it can also be used as a temporary place to put seasonings or pots! 【Size】 Width: Approximately 44cm (up to approximately 78cm maximum) Depth: Approximately 8.2cm Height: Approximately 7.5cm I thought it would be okay because there was an air passage behind the shelf's thickness, so I used it without removing it when using the grill. As a result, dirt from the exhaust vent has stained the steel. I've cleaned off the oily stickiness, but the ingrained burnt stains couldn't be removed. It's a sturdy item, so the dirt and scratches don't affect its use. I checked later, and it said to remove or lay it down when using the grill. It's an expandable type, so you can set it up according to the size of your exhaust vent. (It's not a one-piece type; it separates into two parts when fully extended.) When shipping, I plan to wipe the entire item with alcohol again, wrap it in bubble wrap, and then wrap it in wrapping paper. How about this for those who want to try an exhaust vent cover or those who move frequently? ※Final price reduction.
