Heavy duty three section extension poles collapse to only 4 feet' to allow easy transportation but extend up to 9 feet' allowing users to measure tall windows. The poles feature a ballmount attachment that allows the user to orient the Disto in the proper position for the window being measured. Disto models with a tripod mount can be attached to a magnetic endpiece that easily attaches to the end of the extension pole. By using the timer delay function on the Disto, the user can easily measure windows at heights that would normally require a cumbersome ladder. Fiberglass exterior sleeve with aluminum interior sections.
