ABSTRACT:
A drainage channel installation device comprises a channel-securing member and a channel-hanging member. The channel-securing member releasably engages the channel-hanging member and has opposed ends that are adapted to be releasably secured to the opposed side walls of a drainage channel. The channel-hanging-member has both an engaging end that is adapted to releasably engage the channel-securing member and a suspending end that is adapted to receive and retain a suspending member. As a result, when the channel-securing member and the channel-hanging member are releasably engaged, the channel-securing member is releasably secured to the opposed side walls of the drainage channel and the suspending end of the channel-hanging member receives and retains the suspending member, the drainage channel can be suspended from the suspending member for installation of the drainage channel. The drainage installation device is reusable and allows the drainage channel to be positioned within a trench at any desired level.
