Notes
The Moddex Tuffrail Range is designed specifically under NZS 1657 for places used by operating, inspection, maintenance and servicing personnel. Unlike the Moddex Assistrail range, the Tuffrail design features interruptions on it's top rail, rather than a continuous top-rail. Consequently, it does not align with compliance requirements for use on public access routes. (As per NZBC D1 Access Routes: Handrails shall have a profile which can be readily grasped by an adult hand (32-50mm) and are to have no obstruction to the passage of a hand along the rail).
Evidence
