The Mary Moppins Fiberglass Extension Handle was designed for rigidity, yet lightweight to support your ACME threaded tools. The threads taper (or widen) at the bottom to prevent your tools from twisting loose during use. It extends from 4' to 8', with a 1" outside diameter handle. It is durable enough to handle all of your tough jobs. Flip up the easy release lever to extend the handle. It will help prevent your handle from slipping or locking up while extended. Attach all of Mary Moppins cleaning tools or any of your other ACME threaded tools, including painting tools or push brooms.
