AdirPro Survey Marking Pins 14 in Chaining Pin Set 11-Pack Plastic Line Detector

In surveying, one of the oldest and simplest methods used to measure distances is chain surveying. This method makes use of a surveyor’s chain, which has graduations to help in taking linear measurements. After measuring the distance with the use of this chain-style tape, the next step is marking the points of the lengths. Chaining pins are thus anchored into the ground to mark the points. The AdirPro 14 in. Chaining Pin Set (11-pieces) 765-17 is a helpful accessory to have when you are measuring long distances with a survey chain. These marking pins are made of 7/32 in. (Approximately 3/16 in.) Dia spring steel. They are 14 in. L with a sharpened point. Alternating 1 in. bands of red and white on the middle part of each survey pin help you get all your pins in a row at an even height. The durable powder-coat finish helps protect the pin from rust and corrosion. This Adir chaining arrow set weighs 1.54 lbs. (0.70 kg) per set of 11.
