Barrier (1) for being installed at least partly within a sewage pipe, wherein said barrier (1) comprises two support wings (4) forming an outer shell of said barrier, one or more shutters (6), at least one shutter guide mechanism (7), and a mounting tube (8), and wherein said barrier (1) having a pipe shaped outer shell installable in the sewage pipe, and said barrier having a longitudinal axis X along said pipe shaped outer shell, wherein said shutter (6) is partly covered by said support wings (4), and wherein said support wings (4) are placed along the longitudinal axis X, wherein said support wings (4) are adapted to pivot about a wing hinge (10) positioned on a frame housing (9) of said barrier, wherein said barrier is adapted for having said shutter (6) capable of pivoting about a shutter hinge (15) provided in said frame housing (9) of said barrier, where said shutter (6) having a closed position and a more or less open position, where the shutter (6) is capable of pivoting from a substantially vertical closed position to an angular open position away from vertical in one direction along the longitudinal axis X, where said shutter guide mechanism (7) is capable of controlling said shutter movement direction from a first direction to a second direction opposite to the first direction, along the longitudinal axis X, and furthermore said shutter guide mechanism is capable of adjusting a shutter kip angle a, where shutter kip angle a is the angle from the shutters vertical closing position to maximum angular opening position, and said shutter guide mechanism (7) being capable of preventing the shutter to move in the respective opposite direction to the first or second direction along the longitudinal axis X.

A pipe bracket may be used to secure a plurality of pipes to each other and a substrate, such as the ground. The bracket has a mounting arm having a hole for receiving a fastener. The mounting arm extends between a first free end and a corner. The bracket also has a pipe holding section. The pipe holding section has a stationary end, a flexible end, and a connecting member. The pipe holding section extends from the corner to a second free end at the flexible end. The connecting member includes a first radius section, a second radius section, and a flat bridge such that the pipe holding section defines a containment area for the plurality of pipes having an oblong shape. The mounting arm extends in a plane that is parallel to the substrate.

A lay-flat barrier has a plurality of modules. Each module has two end pipes attached to each other by one or more connecting pipes to form a frame. Each module also has one or more electrically-conductive mesh panels attached on top of the frame. At least one end pipe of each module is connected to an end pipe of at least one other module. Additionally, the mesh panels of the plurality of modules are adapted to be electrically coupled to each other and to a power source so as to discharge a deterrent amount of current upon contact by a small animal.
