US 5,687,514 A · Adjustable curb with flashing

Abstract

A curb is formed of a base portion and an upper portion which fits peripherally over the base. A horizontal clearance between the vertical walls of the base and upper portion of the curb is distributed about the periphery of the curb, to enable the upper portion to be angularly displaced with respect to the lower portion, and to encompass complex as well as linear displacement. The act of leveling the curb is combined with the act of fixing the base with respect to the upper portion which can be accomplished with a simple level and the addition of screws joining the base the the upper portion. A pitch pan area for drainage of water from inside or under the equipment is supported by the curb. The upper partially flat and curved metal structure of the upper portion of the curb provides a surface for gaskets for improved sealing.
