Vertical Cylinder Cappers

Vertical Cylinder Cappers are the most popular design for capping concrete test cylinders. These units maintain the cylinder's orientation perpendicular to the bottom plate assuring end surfaces that are parallel to each other when loaded in a concrete compression machine.

The retaining ring is filled with molten capping compound, and the cylinder is placed into the compound-filled ring and held against the upright guides until the capping compound solidifies. Each bottom plate is ground to 0.002in (0.05mm) planeness, and the vertical guides are removable to permit re-grinding to proper planeness after extended use. The cylinder cappers are also equipped with corner mounting holes, for securing to work surface if desired.

HM-166 for 6x12in (152x305mm) cylinders is a timesaving model with a built-in spring-loaded hand cam lever that tilts the cylinder forward to release it from the capper. The thick 1in (25.4mm) base allows for multiple re-grinding to planeness requirements and an HMA-21 Replacement Retaining Ring is also available to help further extend the life of the HM-166 vertical cylinder capper.

HM-264 for 4x8in (102x203mm) cylinders features vertical uprights to hold cylinders perpendicular to the bottom plate. The 0.625in (15.875mm) thick steel base allows for re-grinding to planeness requirements for extended life.

HM-263 is designed for 3x6in (76x152mm) and 2x4in (50.8x102mm) cylinders and includes a separate retaining ring for each cylinder diameter. Rings on the vertical uprights are adjustable so that the cylinders can be held perpendicular to the bottom plate. Its 0.625in (15.875mm) thick steel base allows for re-grinding to planeness requirements for extended life.
