Focus on the System.
Not the Ladder.
HVAC technicians work at height accessing rooftop units and equipment year-round, often carrying heavy tools and parts. Lock Jaw keeps your ladder secure so you can move safely and efficiently between access points.
OSHA 1910.23 — HVAC technicians working at height on rooftop units are subject to strict OSHA ladder safety requirements. Falls during rooftop HVAC work are a leading cause of serious injury in the mechanical trades.
Every HVAC Tech's
Ladder Just Got Safer
Whether you're servicing residential mini-splits, commercial RTUs, or running refrigerant lines on a new installation, Lock Jaw makes every ladder climb safer and faster.
Rooftop Unit Servicing
Accessing RTUs on commercial flat roofs requires repeated climbs carrying tools, gauges, and parts. Lock Jaw secures each one.
Split System Installation
Installing wall-penetrations, line sets, and indoor units on upper floors — a stable platform even when both hands are full.
Preventive Maintenance
Fast turnaround on PM visits means efficient ladder work at multiple properties per day. Safety without slowing you down.
Commercial HVAC
Multi-story commercial buildings with facade-mounted equipment require long, stable ladder runs. Lock Jaw handles these reliably.
Carry Heavy Tools Safely
Manifold gauges, vacuum pumps, refrigerant cylinders — Lock Jaw keeps you stable when carrying heavy or awkward loads.
Work Alone Safely
Many HVAC techs run solo service calls. Lock Jaw removes the key risk of an unsecured ladder with no ground person.
Year-Round Performance
High-grade nylon and metal construction handles summer heat and winter cold equally well, season after season.
Consistent Safety Culture
Simple enough that every tech uses it every time without being told. Consistent practice across your whole team.
OSHA for HVAC Contractors
HVAC work involving rooftop units triggers OSHA general industry requirements under 29 CFR 1910.23 and construction requirements under 1926.1053 for new-build and retrofit work. Lock Jaw supports a documented, consistent approach to ladder safety that protects your team and your business.
