A metal finishing barrel side opening has a cover secured by a series of cover and barrel tabs, the cover slid into a secured position with the cover tabs partially overlain by the barrel tabs. A locking handle assembly includes a graspable portion supported on a deflectable spring blade attached to the cover at one end which allows the handle assembly to move away from an aligned locator feature on the barrel as the cover is pushed into position. When the cover is shifted lengthwise, the handle assembly moves past the locking feature, and the locking blade pushes the handle assembly back down alongside the locking feature which then prevents reverse sliding of the cover back from under the barrel tabs. When the handle is pulled to initiate removal of the cover, the handle assembly is then moved out above the locking feature to enable the cover to be slid to the released position. An automation apparatus interacts with one form of the locking assembly to automatically install and remove the cover.
