Demanded by our customers, the 400S-D TetraLock^TM, redefines the lightweight metrology stand. It uses one of the strongest structures known - a pre-stressed tetrahedron - to achieve a very high degree of stability.  During setup, cross-brace members rotate down and "snap" into place, forcing the legs to open and lock against a positive stop.  The cross braces are then firmly secured with knurled, collet-type clamps.  This unique design allows the stand to be collapsible, yet virtually eliminates any movement within the joints when locked in the open position.

Features:
The height of the stand is adjusted by releasing quick-action cam style levers and extending (or retracting) each telescoping leg to the desired length.  Index marks on the legs provide visual guides when adjusting the height.  Each leg is outfitted with a "pad style" foot.  On top is a standard 3½"-8 thread on which may be mounted instruments or other adapters.  A bull's eye level vial makes for easy leveling of the stand prior to installing an instrument or adapter.  A duffel style canvas carrying bag with shoulder strap is included with the stand.

Accessories:
You can customize your stand with our 400A-PT Point Feet and/or  400A-W Wheels (see pictures above left).  The wheels are engaged and disengaged simply by unlocking the telescoping leg and rotating it, putting the wheel in an upper or lower position.  Note: The wheel option must be installed at the factory.  Wheels may be installed on stands with either point feet or pad feet.

Our 400A-LT Laptop Shelf (see picture above far right) gives you a convenient location on which to put your computer in close proximity to your measurement instrument.  It is easily installed with a single connecting point under the head of the stand.  Note: Our laptop shelf is often requested by our customers, but such accessories must be used wisely when pursuing high accuracy measurements.
