Mountlaser Tribrach Adapter with Optical Plummet

The tribrach is an essential attachment plate utilized to connect surveying instruments such as theodolites, total stations, GNSS antennas, or targets to a tripod. It allows for precise positioning of the survey instrument over a marker point with sub-millimeter accuracy, achieved by adjusting the instrument base horizontally through the loosening and re-tightening of a lock.

This device comprises two triangular metal plates joined at their corners by leveling thumbscrews, a bubble level, a locking mechanism, and often an optical plummet. The bottom plate's center features a 5/8-11 UNC thread bolt hole for securely attaching the tribrach to the tripod. Meanwhile, the top plate includes three small holes or slots positioned 120 degrees apart above the leveling thumbscrews, along with a locking mechanism that facilitates the precise placement and secure locking of a survey instrument or target on the tribrach.

In summary, the tribrach adapter with an optical plummet is a versatile tool suitable for use with Sokkia, Topcon, or similar styles, providing high quality, accuracy, and ease of use for all your surveying needs. It is the best choice for ensuring precision and efficiency in your fieldwork.
