The ceiling support QS70 is a robust product designed for the professional contractor/tradesman. It is made of high quality materials such as plastic with strengthened glass fibers as well as extra strengthened steel tubes. The device has a patented thumb activated lever for a quick release which allows the product to extend to ceiling height automatically by simply pushing only one button. Top and bottom of the supports have rubber pads (5, 1” x 3, 1“= 13 x 8 cm) with ball joints to accommodate sloping walls and ceilings. The angle of the sloping wall or ceiling is reduced by half (theoretically) preventing the rubber pads on the Quick-Support QS70 from slipping! Application: The professional Quick-Support QS70 (a professional single hand-ceiling support) is preset at a level of approx 4”-8” (10-20 cm) under the ceiling height or under an already installed sheet of paneling, board or drywall. The support can be placed in position, in the middle of a room, with the thumb activated lever for a quick release. There is no need for a wall or other objects to support the device.
