Adjustable pit extension assembly

A meter pit tile extension assembly comprising:

• an inner ring that is attachable to a pit tile;
• wherein the inner ring includes a first set of a plurality of outwardly extending ribs and a second set of a plurality of outwardly extending ribs spaced apart from the first set of the plurality of outwardly extending ribs;
• wherein the plurality of outwardly extending ribs of the first set of the plurality of outwardly extending ribs are each located substantially parallel to each other;
• wherein the plurality of outwardly extending ribs of the second set of the plurality of outwardly extending ribs are each located substantially parallel to each other;
• and
• an outer ring;
• wherein the outer ring is telescopingly positioned over, and vertically movable with respect to, the inner ring;
• wherein the outer ring includes a first set of a plurality of inwardly extending ribs and a second set of a plurality of inwardly extending ribs spaced apart from the first set of the plurality of inwardly extending ribs;
• wherein the plurality of inwardly extending ribs of the first set of the plurality of inwardly extending ribs are each located substantially parallel to each other;
• wherein the plurality of inwardly extending ribs of the second set of the plurality of inwardly extending ribs are each located substantially parallel to each other;
• wherein the outer ring is also rotatable with respect to the inner ring;
• and
• wherein rotation of the outer ring with respect to the inner ring causes the first set of the plurality of inwardly extending ribs and the second set of the plurality of inwardly extending ribs to be selectively positionable in a second position such that at least one inwardly extending rib of the first set of the plurality of inwardly extending ribs is selectively positionable adjacent at least one outwardly extending rib of the first set of the plurality of outwardly extending ribs and at least one inwardly extending rib of the second set of the plurality of inwardly extending ribs is selectively positionable adjacent at least one outwardly extending rib of the second set of the plurality of outwardly extending ribs;
• and
• wherein the outer ring that is vertically movable with respect to the inner ring does not use helical threads to translate rotational movement into linear movement to be vertically movable.
