I place my Weber Summit Charcoal Grill Center into a kind of tight space under the patio. So the fixed wheels can be an issue when I need or want to move it. And because my patio has a slight slope, I need to place boards under the fixed wheels to make it level. I called Weber and explained the situation, and they sent me another pair of castors! And as luck would have it, the castor post on the kettle end is longer than on the table end, so now its level without the boards!! It's sooo much easier to move now, and all ready level.
