Plastic Cylinder Molds with Lip, 4 x 8 inch, No Lid, 50 per Case

Single-Use Plastic Concrete Cylinder Molds

Reliable molds for concrete cylinder testing in the field or lab

Concrete testing starts with a properly cast specimen. Forney Single-Use Plastic Concrete Cylinder Molds are designed for construction materials testing teams that need consistent shape, reliable dimensional integrity, and easy specimen removal without the hassle of cleaning and reusing metal molds.

Made from seamless, non-absorbent, single-piece injected plastic, these molds help maintain a uniform cylinder shape during casting, curing, and handling. The high-visibility orange color makes them easy to spot on the jobsite or in the lab, and the weather-resistant construction holds up well in typical field testing conditions.

After curing, specimens can be stripped using a standard cylinder stripping tool or the Forney Power Stripper. Prepared specimens can then be finished for compression testing using Hi-Cap Capping Compound or Pad Caps, depending on your testing procedure.
