Modular forearm extension

Abstract

A modular forearm extension includes an elongated U-shaped body severed from a member of indeterminate length. A stiffening member is attached to the interior of the body to provide additional strength to the forearm extension. A pair of couplings are fixedly attached to the ends of the body, each having a bore therethrough. The couplings are provided with surface recesses adapted to receive the corresponding shaped ends of the elongated body for attachment and attachment thereto.
