Extremely long and sturdy extendable spirit level that can be adjusted to the required length. The eccentric clamp ensures a high level of accuracy when extended to any position. The upper measuring surface has two small plates to compensate for any irregularities on the surface being levelled. In addition, the two slip-on distance pieces are particularly good for measuring over timber bracing or very uneven surfaces such as bowed timber. Another example of innovative design from STABILA.
