Fast Top clips can be attached to the underside of structural members, concrete decks or floor assemblies. Studs must be cut less than full height to enable vertical movement up to 2-1/2 in. (1-1/4 in. up and 1-1/4 in. down). Fast Top Clips install quickly with welds, screws, or powder actuated fasteners. FastClip deflection screws are used to attach the clip to the cold-formed framing and to ensure frictionless deflection. These clips are also embossed with fastening patterns to ensure accurate placement of fasteners.
