Johnson 40-6340 Heavy-Duty Aluminum Survey Tripod

The Johnson 40-6340 is the explicit preferred tripod for the original truncated Johnson 40-6 catalog entry. Its aluminum legs adjust from 39 to 63 inches nominal length and use quick clamp locks. A 5/8-11 connection accepts compatible instruments. Metal points support outdoor setup, removable rubber covers suit interior surfaces, and safety chains limit accidental leg collapse. These specifications are from the manufacturer’s dated catalog; the mounted instrument is separate.
