0. Application of rubber protection frame

- You can store the safety measuring lines by winding the safety measuring
lines around the rubber protection frame  and engaging the tips of the
safety measuring lines with protection against the rubber protection frame
 (see Figure 14).
- You can engage a safety measuring line to the rubber protection frame 
such that the measuring tip protrudes freely, in order to be able to apply the
measuring tip - jointly with the BENNING MM 11 - to a measuring point.
- The rear support on the rubber protection frame  provides for an inclined
set-up of the BENNING MM 11 (facilitates reading) or attachment (see
Figure 15).
- The rubber protection frame  is fitted with a lug which can be freely used
for an attachment option.
