What to Check Before Buying a Commercial Extension Ladder
Choosing the right extension ladder for commercial use involves more than just looking at the height. You need to consider the duty rating, material, and safety features to ensure it meets the demands of your job site.
Duty Rating: This is the most important spec. For commercial use, you need at least a Type IA (300 lbs) rating. Type IAA (375 lbs) is even better for heavy-duty work. Never use a Type II (225 lbs) or Type III (200 lbs) ladder for commercial jobs, as they are not designed for the stress.
Material: Fiberglass is the standard for commercial ladders because it is non-conductive, making it safe for electrical work. It is also more durable and resistant to weather. Aluminum is lighter and cheaper, but it conducts electricity, so it is not suitable for work near power lines.
Reach vs. Height: The "max reach" of a ladder is not the same as its extended length. A 28 ft extension ladder typically provides a working reach of about 25 ft, accounting for the angle of use. Always choose a ladder that gives you a few extra feet of reach above the surface you are working on.
Rung Locks and Pulley System: Look for smooth, reliable rung locks that engage easily. A rope and pulley system is essential for raising the fly section of the ladder. Test these mechanisms in reviews to ensure they are not prone to jamming.
Warranty: Commercial ladders take a beating. A longer warranty (5 years or more) is a good indicator of build quality. Werner and Louisville offer strong warranties on their fiberglass models.
Mistakes to Avoid When Buying a Commercial Extension Ladder
Even experienced contractors can make mistakes when selecting a ladder. Here are common pitfalls to avoid.
Buying a Ladder That Is Too Short: This is the most common mistake. A ladder that is too short forces you to overreach, which is a leading cause of falls. Always buy a ladder that provides at least 3 feet of extension above the roof line or working surface.
Ignoring the Duty Rating: Using a ladder with a duty rating too low for your weight and tools is dangerous. Always add the weight of your tools and materials to your own body weight when selecting a duty rating. A Type IA (300 lbs) is the minimum for commercial use.
Choosing Aluminum for Electrical Work: Aluminum ladders are conductive and can be deadly if they contact live wires. For any work near electrical sources, fiberglass is the only safe choice. Never compromise on this safety feature.
Forgetting About Storage and Transport: A 28 ft fiberglass ladder is heavy and long. Make sure you have a way to transport it (roof rack or truck bed) and store it securely. Aluminum ladders are lighter but less durable for daily commercial use.
Buying Based on Price Alone: The cheapest ladder is rarely the best value for commercial use. A higher upfront cost for a quality brand like Werner or Louisville often pays off in durability, safety, and warranty support over the long term.
