Abstract: An adjustable sink positioning and mounting apparatus for rapidly attaching sinks to the underside of a counter top includes a channel base member with means for attaching to a cabinet wall, a blade spring with an angled portion at a lower end of the channel base member, and an elongated sliding member releasably engaged with the channel base member. The sliding member includes one of teeth or threads and an arm adjacent the top end.

Abstract: An undermount sink mounting system includes a support member adapted to engage a frame onto which a countertop is mounted. The support member upwardly supports a sink engagement lever, which is adapted to engage a sink in such a way that said sink engagement lever presses the sink upwardly toward the countertop when the sink is mounted. A height adjustment member is adapted to move the sink engagement lever upwardly to engage the sink and adjust how forcefully said sink engagement lever presses against the sink.

Abstract: A sink comprising a basin, a rim extending outwardly from the basin, a support member in the form of a channel coupled to an underside of a portion of the rim to increase the rigidity of the rim, and a mounting element operatively coupled to the channel and configured to secure the rim to a fixture.

Abstract: A waste trap 10 for use in plumbing installations is provided, the trap comprising a unitary metal body 12 defining an interior volume, and having a tubular plastics insert 20 located in an inlet 14 of the body 12 and extending into the volume to below the height of a waste outlet 16. The insert 20 partitions the upper portion of the volume into two regions, and serves to provide a water seal between the inlet 14 and the outlet 16 when the trap is in use. The insert is non-removably secured to the body.

Abstract: Methods are disclosed for mounting an undercounter sink provided with a flange by means of a removable metal collar, which is used: to precisely locate and position the sink beneath a laminated countertop: and to finish cut at the installation site the countertop aperture and the top impervious surface of the countertop to form a flush, watertight seal.

Abstract: A cooktop has its body disposed within a rectangular shaped opening in a counter top. The body has upper front and rear flanges larger than the opening in the counter top to rest on the counter top. The cooktop has two slidably mounted clamping brackets on its bottom surface with one at its front edge and the other at its rear edge. Each clamping bracket is releasably held in a retracted position within the periphery of the bottom surface of the cooktop during insertion of the cooktop into the opening. Each clamping bracket has two elongated slots through which two screws extend into two holes in the bottom surface of the cooktop. After the cooktop is inserted within the opening in the counter top, the two screws for each clamping bracket are loosened, and each clamping bracket is moved to an extended position with its maximum being the length of the elongated slots. Each clamping bracket has a nut to receive a long screw.
