It is generally used in conjunction with a spirit level or engineering measuring ruler. The spirit level is placed on the wall or on the ground, and then plugged in with a wedge feeler to detect wall, ground levelness, and verticality errors.

Wedge feeler, generally made of metal, has a scale on the oblique side, a field measurement tool for construction.

Generally match the spirit level, place the spirit level on the wall or the ground, and then plug it with a wedge feeler to detect the wall, ground levelness, and verticality errors.

It is generally used in buildings to check flatness, levelness, gaps, etc., and also directly check the door and window gaps.
