Thorlabs' Optical Table Earthquake Restraints are designed to reduce and/or stop movement of an optical table top during seismic activity. The restraints are minimally invasive, with the ability to withstand a combined table top and equipment load of 5500 lb (2500 kg) at 1.4 g of lateral acceleration. These restraints have been certified to comply with International Building Code (IBC) 2009; for more information about this certification, please contact tech support. They are available in two heights, 23.5" (600 mm) or 27.5" (700 mm), which matches the height offerings of our optical table supports.
The restraints are designed to be secured into a masonry floor with bolts appropriate for the particular floor type. Since floor structures vary, bolts are not supplied with the restraints; please contact tech support for more information.
In order to mount these supports to an optical table, holes must be added to the underside of the table for attaching the restraints. This is most easily done when the table is purchased; if possible, please order these restraints at the same time you are ordering your optical table to ensure proper fit. For modifications to previously purchased optical tables, please contact tech support. Note that these earthquake restraints are not shipped from stock and all orders will incur a lead time.
