There are numerous different configurations of an industrial container. When determining which container is appropriate for a specific use, businesses consider the container’s material, gauge or thickness of the material, size, shape, linings, closures, head style, and many more factors. Some of these factors come with a multitude of options, for head style, it is just a choice between two: open head or tight head.
So what is the difference between an open and tight head drum?
An open head container, also called 1A2 drums, has a fully removable cover secured with a Lever lock or bolt ring closure. Tight head drums, also known as closed head or 1A1 drums, have a non-removable top. One can only access the container via a 2” and ¾” plug in the top of the container.
On a tight head drum, the head is an integral part of the drum construction — both ends are flanged and permanently sealed. Because of the limited access to the contents, tight head drums are often used for liquids, especially lower viscosity liquids. For example, Skolnik’s stainless steel wine drums are tight head containers.
Open head drums, on the other hand, are used for a wide array of contents. Skolnik’s lever lock closure drums are UN rated for solids and liquids, particularly thicker liquids such as soil absorbents, syrups, glues, oils, etc. Open head drums are typically used in situations where people need access to the contents, either for frequent addition or extraction.
Skolnik Industries manufactures both open head and tight head steel drums in over 500 configurations, always to UN and DOT certification standards. If you are unsure what style head or closure your contents require, don’t hesitate to ask a Skolnik representative.
