Needed replacement cover for a Ducane 4420. OE cover from mfg was too tight and after about 3 yrs sharp corners on the grill tore the cover. Next was cheap replacement from big box home improvement store that barely lasted the season and hung on the grill like a too big coat. It had no discernable front or back. I just received this cover and I feel like Goldilocks - it is just right!. The size is perfect. Nice fit but not so tight it is difficult to get on and off. Quality is perfect. Nice heavy material which appears to be well constructed. I would have gotten the 10 yr cover, but figured my grill might not last as long as the cover, so this one with the 4 year warranty is just right.
