The LocKing Cover Secures Manholes Covers in Place

Watch the LocKing^SM Video

The Lifter^SM is the opener, or “key,” to The LocKing^SM Cover. The Lifter^SM is used to release the locking mechanism. With The Lifter’s^SM magnet activated and the locking mechanism retracted, the cover can be removed with ease.

The LocKing Cover can be purchased new or retro-fitted to existing covers.

The operator threads a pin into the
bottom of the Lifter’s^SM magnet. Note the
pin just visible below the magnet.

The Lifter’s^SM hydraulics exert
pressure downward, overcoming
the 500 lbs. of spring pressure.

The Lifter^SM easily removes the
LocKing^SM Cover. Note the
retracted arm.
