Rated 5 out of 5Â by steve1234 fit my needs
much more sturdy than trying to use two 3.5 inch extensions. it also allowed me to offset it to the side so that the rail was not over the opening. the only issue i had was the slow shipping compared to other major retailers. it was processing forever... i ordered another size from another major online retailer and it was here a full week before the one from kohls.com.
