Medium Weight "POP-OFF"® FLASKS
These rugged flasks are heavy enough for most machine production jobs, yet light enough for the bench.  Jig and fixture built for maximum accuracy and strengthened with the familiar HINES diagonal ribs.  Moreover, "POP-OFF" flasks needn't be pounded for removal, no matter how heavily sand is rammed.  Simply move the handles and off they pop!  And, they last longer!
Serrations on the inside surface eliminate the need for sand strips-cope and drag sand is anchored so firmly there's no possibility of shift from vibration.  These serrations also provide for perfect venting of the mold.
Two-part flasks are generally equipped with the standard No. 70 "POP-OFF" locking assemblies, shown in flask at right.  The flask at left has the clevis closing mechanism that provides for simultaneous opening of two or more sections.
