Abstract
A traffic signal housing particularly suitable for moulding modular units frm engineering thermoplastics. The back body portion is generally cylindrical; each end portion of the cylinder is reinforced with radial webbing connecting to a coaxial inner cylinder, thus forming a stiff load transfer structure extending into the housing to a depth of about 10 percent. The peripheral edges of a one load transfer structure are shaped to mate and seal with those of an adjacent unit. Units are coupled with a pipe bolt passing through adjacent inner cylinders to place the reinforced ends under compression. Thus assembled units have a great rigidity and load may be transmitted without the undue flexing or cracking common in prior known units.
