The ERS2010-322 Earthquake Restraint system is designed to restrict the motion of optical table top during seismic activity. Model ERS2010-322 is rated for seismic forces generated by a maximum of 2000 pounds (908 kg) of combined table and payload weight per restraint. ERS2010-322 earthquake restraint is certified to comply with the 2012 International Building Code (IBC) and 2013 California Building Code (CBC). Model ERS2010-322 is a set of (3) 22 inch earthquake restraints. Anchors are not included and must be ordered separately (see ERS2010-KT anchor kits). ERS2010 restraints will not affect table performance.
