A system for attaching a mounting wall of a screed extension to a screed assembly including a first mounting component configured to be engaged within a first receptacle provided on the mounting wall. The first mounting component includes a first fastening member. The system further includes a second mounting component configured to be received within a second receptacle provided on the mounting wall. The second mounting component includes a second fastening member to engage with the first mounting member on the mounting wall and a mounting catch to engage with a mating wall of the screed assembly.

Screed extension attachment system

An extendable screed has independent height and angle of attack adjustment for a lower extender frame. At least one post and cylinder assembly are used to couple the lower extender frame to an upper extender frame at a pin that allows rotation of the lower extender frame relative to the upper extender frame. A vertical adjuster uses a drive rod with a pivoting attachment at the lower extender frame. An axis of rotation of the pin and an axis of rotation of the pivoting attachment are co-linear. This arrangement allows lower extender frame to move vertically while allowing angle of attack adjustments to be made about the co-linear axes of rotation. Simple screw adjusters displaced from the axis of the pin and collet assemblies allow raising and lowering the back of the lower extender frame to adjust the angle of attack.
