Frequently Asked Questions
Q: What thread size does this composite extension tube use?
A: This extension tube features a standard 5/8"-11 thread on both ends — a 5/8"-11 male and a 5/8"-11 female interface — making it compatible with most surveying tripods, RTK GNSS antennae, robotic total stations, and other standard mounting accessories.
Q: Can multiple extension tubes be stacked together?
A: Yes! Because each tube includes both male and female 5/8"-11 threaded ends, you can connect multiple rods in series to achieve your desired total length. Simply thread them together and tighten firmly for a secure connection.
Q: What materials are used in this extension rod?
A: The rod is constructed from a combination of carbon fiber and aluminum alloy. This composite design provides excellent rigidity and structural durability while keeping the overall weight low — ideal for field use with surveying and measurement equipment.
Q: Which length should I choose?
A: Six lengths are available — 10cm, 20cm, 30cm, 40cm, 50cm, and 60cm. Choose based on the height extension needed for your specific application, such as GNSS antenna height measurement or tripod stabilizer setups. Multiple rods can be combined for greater reach.
