ABSTRACT:
A spirit level having a sub-assembly on the body. The sub-assembly has a vial holder having two spaced pockets. A curved vial having two ends received in the pockets and resilient ribs having a curve matched to the vial and engaging the vial to hold the vial in an adjusted position. Each vial can be adjusted relative to a separate vial holder and each vial holder/vial sub-assembly can be independently adjusted and set relative to an appropriate edge of the level. The vial snaps into a fixed receptacle on either side of the vial holder. One side of the holder is curved to match the curve of the vial to insure that the vial is properly positioned. The underside of the vial holder may be relieved to increase flexibility to make it easier to snap the vial into place.
