Abstract: A curb inlet having a removable non-concrete gutter form, which is an arcuate, generally rectangular strip having a concave front face and a convex rear face with a plurality of handles secured to the rear face and, also secured to that rear face, a plurality of aligning horizontal sleeves each having a tube portion and a latch portion and each having a locking bolt slidably mounted in the sleeves. The form can be locked in place in a pre-cast curb inlet member by the bolts entering openings in that pre-cast member. The form retains concrete when the concrete is poured against the pre-cast member. After the concrete sets, the bolts are withdrawn from the openings and the form can be removed through an access opening therein. The form strip may be a fiberglass-plastic resin structure.
