When you grab a bucket, you most likely will need a lid. Stuff will fall out if you don’t cover it. Hence, Best Containers' covers for plastic pails and containers. You want to color code your product? Use the different color options we have in our lids. You need a spout for pouring? Use Best Containers' covers with the flexspout in it. Just remember to grab the UN Rated covers if you are shipping hazardous chemicals. The plain lids will not help you meet those requirements. Oh, and don’t forget the handy convenience of the Gamma Seal lids. These things are great. You can easily access inside your pail without having to fully remove your lid. Helps your job move a little faster. Make sure you use our buckets, as these lids are only designed to fit on these pails.
