This level is for all those who need both hands free when aligning and levelling on steel frame structures. The 81 SREM has a rare-earth magnet system with strong holding-power. The bevelled shaped level has a die-cast aluminium body which makes it one of the sturdiest levels that STABILA makes. The vials are precisely aligned with the milled measuring surface then locked together ensuring maximum accuracy. This gives the 81 SREM an exceptionally long working life on building sites.
