Abstract: A mud flap bracket assembly comprises a functional frame bracket assembly and one or more interchangeable bracket covers. The frame bracket assembly has unitary frame bracket that is formed from a sheet metal blank that is configured to form and integral spring mount and integral slots to mount a frame seat. The frame bracket has integral slots that mount mud flap clips that are adjustable within the slots for mounting mud flaps of different hole configurations. The frame bracket assembly is assembled with integral fasteners and without welds.

Abstract: A precast concrete slab connector for connecting two adjacent slabs in edge-by-edge juxtaposition, each with a recess in registry with a recess in and an adjacent slab. A pair of anchor plates are positioned the slab recesses and a shear plate spans the slabs recesses and overlies the anchor plates. The shear plate has openings that are in registry with one of an anchor plate opening. Multiple fasteners are extend through the openings in the anchor plates and the shear plates and include removable retainers that clamp the shear plates and the anchor plates together. The fasteners can be cast in part into each adjacent slab. Serration can be provided with facing surfaces of the anchor plates and the shear plate or on facing surfaces of the shear plate and washers that are mounted on the fastener.

Abstract: A roll-up door has a plurality of panels and a plurality of roller assemblies mounted to ends of the panels for mounting the panels in channels. At least some of the panels are formed of blow-molded thermoplastic material and have a relatively flat outside face and an inside face including ribs that extend longitudinally and transversely on the panel. A reinforced panel of thermoplastic material is made by blow molding a panel with a thermoplastic material to form a relatively flat outside face and a ribbed inside face, and with elongated channels along upper and lower walls thereof. The panel is trimmed while it is still warm to open the channels at one end. While the panel is still warm, reinforcing members are inserted into the elongated channels. The panels are cooled to shrink the channels onto the reinforcing members.

Abstract: An adjustable fender vehicle has an upper wall with inner and outer side walls. The inner side wall includes an elongated longitudinal clamping edge and an interior wall depends from the underside of upper wall between the inner and outer walls. The interior wall has an elongated longitudinal opening in registry with the elongated longitudinal clamping edge in the inner side wall for receiving a fastener for adjustable mounting of the fender to a vehicle. The inner side wall includes an elongated longitudinal opening in registry with the elongated longitudinal opening in the interior wall and the elongated longitudinal clamping edge is formed in the elongated longitudinal opening in the inner side wall. The elongated longitudinal opening is configured to receive a mounting arm that is adapted to extend through the elongated longitudinal opening to the interior wall. Fasteners on the mounting arm clamp the fender to the mounting arm.

Abstract: A vehicle fender is mounted to a mounting arm through at least one clamp that is mounted on the mounting arm. The clamp and an edge of the fender have complementary teeth and grooves to adjustably mount the fender to the mounting arm. The fender teeth and grooves are formed in a pocket and the pocket extends beneath the fender panel and receives the mounting arm.
