Ribrachs are designed for use with our other products and meet or exceed the quality and construction standards of leading Japanese, Swiss, and German brands. The tribrach has a support system that ensures stability in all environments. It’s also a good idea to add an image to your listing – people process visuals much faster than text and it helps potential buyers to see the exact condition of an item. To create the most effective image, keep the following in mind: The image should be taken against a solid background – focus on the item and try to show as many details as possible. Tribrachs offer precise plumbing of surveying instruments and adapters, and have a universal 5/8-11 base plate. As in a tripod, stability in a tribrach is a significant factor in measurement accuracy. The torsional rigidity, the most important criterion of a tribrach, is constantly controlled and tested during its production. The precise alignment of the support area to the base plate of the instrument assures extremely accurate forced centering.
