I wanted to get a good cover to help maintain the work I did getting my CL RK all cleaned up. After searching around the Internet, I took a chance on a cover that I thought would fit.
Before - tarp with bungee cord. Not desirable for long term use.
After - looks like it was made for it.
Here is the site
http://www.the-cover-store.com/.
They sell three different types of covers. I went with this one.
http://www.the-cover-store.com/item_detail.aspx?ItemCode=CSP15419GY3&CategoryCode=patio_table_coversThis is made for a round table, but the dimensions are close to the ranch.
It seems much better than the covers you get from weber. Has a drawstring and elastic band around the bottom. It also has some side vents. Should last longer than the Weber covers. It was $64 but I think it was worth it.
Thought others with a RK might like the info. I always keep my grills covered when not in use since we have a lot of trees in the backyard that drop stuff most of the year.
