Abstract: An apparatus includes a blind flange and a clamp configured to clamp the blind flange to a pipe flange in sealing engagement. The clamp includes a body and a latch. The body is configured to extend around the blind flange and the pipe flange and includes a first portion and a second portion movable with respect to the first portion. The latch is configured to secure the body on the blind flange and the pipe flange. The clamp also includes a plurality of wedges spaced circumferentially about the body and rotatably connected thereto. The latch is selectively adjustable to move the first portion of the clamp body towards the second portion of the clamp body such that the plurality of wedges engage respective outer surfaces of the blind flange and the pipe flange to press the blind flange against the pipe flange.

Abstract: A door lock includes a base and a lock bar moveably coupled to the base. The base includes an angled top wall and a bottom wall, and has at least one channel defined therein. The lock bar includes at least one rod having a first end coupled to the lock bar and a second end that extends into the at least one channel. The lock bar further includes a top wall and an angled bottom wall that is oriented at substantially the same angle as the base top wall such that the base top wall and lock bar bottom wall are substantially parallel to one another. The lock bar is moveable relative to the base from a first position to a second, engaged position, in which the second end of the at least one rod protrudes from the base bottom wall.
