Rob Allen American Square Notch Wire Finned Speargun Shaft

Overview

The Rob Allen American Square Notch Wire Finned Speargun Shaft is a carbon spring-steel shaft designed for spearguns with American-style trigger mechanisms. Its square-notch rear profile provides the trigger interface, while wire fins provide engagement points for the speargun bands.

Fit and compatibility

The square-notch interface is specific to American-style mechanisms and differs from the interface used by Rob Allen spearguns. Confirm the speargun's trigger mechanism before selecting this shaft, as it is not compatible with Rob Allen speargun mechanisms.

Construction

The hardened carbon spring steel is rated at 50 to 52 Rockwell C with a stated tensile strength of approximately 2000 to 2100 MPa. This construction is intended to provide resistance to permanent bending under the loads encountered during spearfishing.
