TMC - SYSTEM 1 6-Post Support Systems with Tiebars, Rigid Supports

Vibration Isolation Gimbal Piston™ Isolators and Rigid Supports

6 Post System with TieBars

Most tops more than 10 ft (3 m) long are best supported by the 6-Post System with Tiebars. In addition to the higher weight capacity, the structural characteristics of the top are enhanced by the additional support points

How to order:

Determine whether vibration isolation is required or whether rigid, non-resonant support is adequate.
Choose whether or not the caster option is desired.*
Find the size of the optical top to be supported in the left column of the ordering chart.
Pick the model number from the appropriate column.
Assign the height code (H) to the catalog number based on the desired height of the table surface and thickness of the optical top.
Ensure that the support has adequate capacity by comparing the capacity to the optical top weight plus equipment load. Top weight is equal to the top area times the weight factor from the bottom of the optical top size charts. The isolator capacity should be at least double the total load.
Contact TMC when in doubt and for unusually sized tops.
*Casters can only be used with post heights of 18 in. and taller.
