An apparatus for sealing an opening in a metal sheath surrounding an insulated pipe is provided, the apparatus including a base comprising an outer flange securable within the opening, and defining an inner passage therethrough, the base having an annular ridge extending into the inner passage; a flexible waterproof body positionable within the inner passage, the body having a periphery therearound and a groove located within the periphery adapted to engage around the annular ridge; and a flexible metal element within the base.

A reinforced flexible seal (101 and 201) for sealing a gap or space, such as a gap or space between an edge of a wall, fence, door, door leaf or wing, port or window and a surface adjacent to the wall, fence, door, door leaf or wing, port or window is provided. The flexible seal may be used to provide a barrier below a door leaf or door wing in order to avoid entrance of for example unwanted animals. The reinforced flexible seal has a width and a length and comprises a flexible outer material (102a, 102b, 202a, 202b), and a plurality of elongated metal wires (103, 203) embedded in the flexible outer material and running substantially in a longitudinal direction of the reinforced flexible seal with at least part of said elongated metal wires arranged at a distance to each other. For at least one of the embedded elongated metal wires, at least part of said metal wire holds several bent, bulging or wavelike deformations in the longitudinal direction of the wire.

A flexible and oblong blade seal for sealing a gap between a door leaf and an adjacent surface including a flexible outer material and a section with the sealing function in which a barrier of a plurality of substantially parallel metal wires and/or narrow metal strips is embedded in the flexible outer material. The wires and/or strips are arranged in parallel to the longitudinal direction of the seal, where at least a part of at least one of the metal wires/or strips is provided with 3 or more stable bends The bends selected from a curve-shaped bend, a bulging deformation, a wave-shaped bend and a wave-like deformation.

Systems and methods for rectifying excessive bottom or head clearances of door assemblies are disclosed. An example system may comprise a door sweep installed on a first side of a fire door; a door shoe installed on a second opposite side of the fire door; an intumescent seal in an opening between a bottom edge of the fire door and the door shoe or a floor surface; and end caps installed on two narrow side ends of the fire door.

Systems and methods for rectifying excessive bottom or head clearances of door assemblies are disclosed. An example system may comprise a door cap straight component installed on a first side of a fire door; a door cap L-shaped component installed on a second opposite side of the fire door; at least one intumescent strip seal fitted with the door cap L-shaped component; and end caps installed on two narrow ends of the fire door.

A device for sealing an aperture defined between a first object and second object is provided. The device comprises a first sealing member and a second sealing member. The first sealing member comprising a base member and first, second and third sealing portions. The base member has first and second sides and a surface extending therebetween. The first sealing portion extends from the first side of the base member. A first attachment portion extends along at least a portion of the surface of the base member. The second sealing portion extends from the second side of the base member and is configured to conform to and seal the gap. The third sealing portion extends from the second sealing portion and defines a distal end structured to conform to and form a seal the exterior surface of the second object. The second sealing member comprising a backing member and second attachment portion. The backing member comprising a first and second surface, wherein the first surface comprises an adhesive structured to attach to the first object. The second attachment portion extending along at least a portion of the second surface of the backing member, and being configured to matingly engage the first attachment portion to thereby secure the first sealing member to the second sealing member and to thereby sealing engage the second sealing portion at least partially within the gap and sealing engage the distal end of the third sealing member with the exterior of the second object.

A door arrangement has a door frame, a door leaf, door hinges and a magnetic closure device, wherein the door hinges are fastened on a hinge side of the door leaf and join the door leaf swivelably with the door frame. The door frame has a step for stopping the door leaf in the closed position, the step having a stop arm overlapping the door leaf in the closed position and a lateral arm. The closure device is formed from a magnet arrangement on the door frame as well as a magnetic material on a rim of the door leaf. The magnet arrangement is disposed on the lateral arm in such a way that a gap remains between the magnet arrangement and the magnetic material disposed on the rim of the door leaf.
