Abstract
A well cover arrangement is shown for covering the exposed opening of a well where the well has a submersible pump supported on a collared well string which is suspended downwardly in the well. The cover arrangement includes both a U-plate with a U-shaped opening therein and a door element which fits within the U-plate opening. Once the door element is properly positioned on the U-plate, cooperating locking elements maintain its proper position. The ultimate weight of the well tubing string further secures the door element as the collar in the well string contacts a portion of the door element, making removal of the door element only possible by first lifting the well string.
