Abstract
A low-profile catenary hanger, catenary wire system, and a method for supporting an electrical contact wire in relation to a messenger wire wherein a wire clamping assembly clamps about the contact wire, and a wire corral assembly is fixed to the clamping assembly. The corral assembly defines an adjustable reception corral through which the messenger wire is received without fastening so that the contact wire can rise without a consequent lifting of the messenger wire. The clamping assembly has a first clamping member with a keystone-shaped projection and a second clamping member with a keystone-shaped slot that can slidably receive the keystone-shaped projection to fix the clamping members together by operation of a setscrew. The clamping members together define a wire reception volume, and each clamping member has an engaging tooth whereby a contact wire with opposed longitudinal grooves can be clamped and retained by the clamping assembly.
