The Original 3rd Hand not long enough?
If you need to go super high, buy the EMT Kit, get down to your local hardware store and buy some lengths of EMT (Electrical Metallic Tubing) that are normally available in 3m lengths and extend the reach of your Third Hand to reach up to 6.6m off the ground!
Please note – When using the EMT Kit at extended lengths, it is recommended only to be used as a dust barrier system, not normal load capacity.
Or the other option is to connect two Third Hands end-to-end and reach 5.5m ceilings. It was designed to enable you to create a dust barrier or laser mount above 3.6m. It connects in seconds and the tension collar gives a secure fit. Because you have a Third Hand close to the ground you can ratchet it into position easily.
