Cube Maker System utilizes disposable polypropylene mold liners that fit into a permanent three-gang stainless steel frame. Cured cubes are lifted out of the frame and the liners are stripped away. The reusable frame never needs cleanup. The system includes 27 Poly Liners, four unbonded caps and two stainless steel retainers. Two red caps are for strengths up to 4,000psi (27.6mPa) and two amber caps are for strengths exceeding 4,000psi. The caps may be reused up to 300 times. This inexpensive, timesaving system is reliable for in-house quality control and other non-specification applications. Liners, pads, and extra mold frames are available separately.
