Portable Industrial Stands for Laser Trackers, Articulating Arms, Laser Projectors, Scanners, Total Stations, Theodolites, and more.


When customers asked Brunson to engineer a lightweight industrial stand, they turned to one of the strongest structural elements known - a pre-stressed tetrahedron for ultimate stability. Made from aluminum and stainless steel, the TetraLock and the TetraLock Lite include pad feet, a choice of thread adapter, and a duffel style carrying bag. These portable stands can be checked in as luggage or stowed in the trunk, and used on tables or platforms.

Engineered for extreme stability, the lightweight TetraLock stand weighs just over 20 lbs. with a maximum height of 47". Due to the TetraLock's unique design, no joint movement is possible when locked in the open position. The TetraLock Lite featherweight stand weighs in at 16.2 lbs. also with a maximum height of 47". It deploys rapidly by tightening a locking plate under its mounting ring.

Both designs offer the best price/performance ratio in the marketplace.


The height of the stand is adjusted by releasing quick-action levers and setting each telescoping leg to the desired length. Index marks on the legs provide visual guides when doing this. Each leg is outfitted with a "pad style" foot. The TetraLock may be purchased with one of three thread mounts: 3½"-8, 5/8"-11, or 3/8"-16. A duffel style canvas carrying bag with shoulder strap is also included with the stand.

  • Bubble level (on TetraLock only)
  • Easy transport, fast setup
  • Cross braces are rotated down and snap into place, secured with knurled, collet-style clamps. This forces the stand into a pre-stressed, pyramid-like shape, locking each leg against a positive stop.
  • The more economical Tetralock Lite deploys by tightening a locking plate under its mounting ring.
  • Each stand is collapsible for storage, yet has no movement within its joints when locked in the open position.
