This telescoping connector allows you to sleeve 1/2" EMT conduit into 3/4" EMT conduit. The lower set screw secures the clamp around the 3/4" pipe, and the upper handle allows you to easily loosen to adjust the height of the inserted 1/2" pipe. These clamps are made of a high quality plastic rather than steel. They are perfect for lightweight projects that need adjustable pipes!
