Focus on the System.
Not the Ladder.
Air conditioning and refrigeration technicians work at height year-round in the Australian climate — accessing rooftop units, split systems, and condenser equipment in 40-degree heat and driving rain. Lock Jaw keeps your ladder secure on every callout.
WHS Act 2011 & ARCtick Obligations — HVAC and refrigeration technicians working at height on rooftop units are subject to WHS Regulation 306. Falls during rooftop HVAC work are a documented source of serious injury in the Australian mechanical services trades.
Every Australian HVAC Tech's
Ladder Just Got Safer
Whether you're servicing ducted systems in a Brisbane Queenslander, installing a new split system on a two-storey Sydney home, or maintaining a rooftop package unit on a Melbourne warehouse — Lock Jaw makes every ladder climb safer.
Rooftop Package Unit Servicing
Accessing RTUs on commercial flat roofs under the Australian sun requires repeated, safe climbs carrying tools, gauges, and parts. Lock Jaw secures each one.
Split System Installation
Installing wall penetrations, refrigerant line sets, and indoor units on upper floors — a stable platform even when both hands are full.
Preventive Maintenance Callouts
Fast-turnaround PM visits across multiple residential and light commercial properties. Safety without slowing down your tech's day rate.
Commercial HVAC
Multi-storey commercial buildings with facade-mounted condensers and eaves-level equipment require stable, repeated ladder access throughout the year.
Carry Gauges & Equipment Safely
Manifold gauges, vacuum pumps, refrigerant cylinders — Lock Jaw holds the ladder firm when carrying heavy or awkward equipment.
Safe for Solo Technicians
Many HVAC techs run solo service callouts. Lock Jaw removes the primary risk of an unsecured ladder with no second person present.
Handles Australian Conditions
High-grade nylon and metal withstands north Queensland humidity, south-east Australian heat, and alpine cold conditions.
Builds a Safety Culture
Simple enough that every tech uses it every time without being asked. Consistent safe work practice across your whole team.
WHS for HVAC & Refrigeration Contractors
HVAC and refrigeration work involving rooftop units above 2 metres triggers high-risk construction work provisions under the Model WHS Regulations, requiring a documented SWMS. AIRAH encourages documented safe work procedures as best practice for member businesses. Lock Jaw fits directly into your SWMS as a verifiable control measure.
"Our techs are on rooftops in 38-degree heat through summer, then back up there in winter. Lock Jaw is now on every ladder we own. The WorkSafe inspector loved seeing it — asked where he could get one for his own business."HVAC Business Owner — South-East Queensland
