The duct end bracket is used to fasten the open end of a standard 50mm straight duct to the top of a rack. Supplied loose are 3 x short lengths of double sided, adhesive backed fastening tape that are used to secure and hold the end bracket onto the rack. The end bracket simply snaps into the end duct slots. It can be removed with a screwdriver if necessary. For a stronger holding connection to the rack, 4 x 3mm dia holes are provided for securing screws.
