A seal assembly, including a first conduit member having a first seat and a second conduit member having a second seat. The second conduit member is coupled to the first conduit member such that the first and second conduit members are moveable between at least a rest configuration in which the first and second seats are a rest distance apart, and a compressed configuration in which the first and second seats are held at a compressed distance apart. The compressed distance is less than the rest distance. The seal assembly also includes a flexible seal received between the first and second seats such that the flexible seal is compressed when the first and second conduit members are in the compressed configuration, the flexible seal expanding axially outwards when compressed to engage with an inner surface of a body in which the seal assembly is received.

A system for controlling rain water flow includes a container having a top end and an opposite bottom end. A drain tube having a drain port is connected to the container. A cover tube slidably receives the drain tube. A magnetic latch is disposed between the drain tube and the cover tube. The system includes a fill configuration in which the magnetic latch is magnetically engaged and the cover tube covers and seals the drain port of the drain tube. The system also includes a drain configuration in which the magnetic latch is magnetically disengaged and the drain tube slides downward to expose the drain port.

A rain gutter system with a first elongated member and a second elongated member is disclosed. The first elongated member may include a first interior surface and a first exterior surface. The first interior surface may include an elongated retaining shoulder disposed along a first elongated member length. The second elongated member may include a second interior surface and a second exterior surface. The second exterior surface may include an elongated ridge disposed along a second elongated member length. The second elongated member may be configured to slide inside the first elongated member along the first elongated member length, and the elongated ridge may be configured to engage with the elongated retaining shoulder when the second elongated member slides inside the first elongated member.

A modular portable wheelchair ramp canopy configured to fit over and protect a wheelchair ramp from rain. The canopy has a gutter that channels rainwater into the canopy uprights and then down to the ground. The canopy also has an end section that slopes back to a gutter which collects rainwater and channels it into canopy uprights and then down to the ground.
