Steel Band

The steel band, also called the band chain, consists of a ribbon of steel with a brass swivel handle at each end.
It is 20 or 30 m long and 16 mm wide.
It is wound on open steel cross, or on a metal reel in a closed case.
The graduations are marked in two ways: (a) The band is divided by brass studs at every 0.2 m and numbered at every l m, the first and the last link being subdivided into cm and mm, (b) The graduations are etched as meters, decimeters, centimeters on one side and 0.2 m links on the other.
Brass tallies are fixed at every 5 m length of the band. It is best adapted to general field work and rough usage. For accurate work, the steel band is now preferred.
It is lighter and easier to handle than the chain. It is practically unalterable in length. It must be protected from rust by frequent cleaning and oiling.
