Werner 20' Fiberglass Extension Ladder Type IA (D6220-2): Non-Conductive Protection at 19-Foot Heights

Worth it for electrical contractors who need non-conductive rails and 300 lb Type IA capacity. The ALFLO twist-proof connection between rungs and rails creates a rigid ladder that won’t flex under load, and the dual-action swivel feet handle both concrete surfaces and penetrable ground.

Skip it if you’re only doing basic homeowner tasks. This ladder is engineered for professionals who need electrical safety and heavy-duty capacity.

Safety and Construction for Montana’s Electrical Work

The fiberglass construction makes the ladder safe for work near electricity — critical when you’re maintaining rural power lines or wiring commercial buildings. ANSI A14.5 certified and OSHA compliant, this ladder meets the safety standards Montana contractors need for jobsite compliance.

Specification	Value
Load Capacity	300 lbs
Duty Rating	Type IA (Extra Heavy-Duty)
Weight	40 lbs
Closed Length	10.5 ft (126 in)
Width	19.5 in
Total Number of Rungs	20

The 1.625-inch Traction-Tred aluminum D-rungs give you secure footing even with muddy boots. Werner’s ALFLO twist-proof rung joint eliminates the flex you get with cheaper ladders — when you’re 17 feet up running wire, that rigidity matters.

Professional Features That Earn Their Keep

Shu-Lok feet with slip-resistant pads and spur plate adapt to whatever surface you’re working on. Set up on concrete at a commercial site, then move to soft ground for utility pole work — the feet adjust without tools. The gravity-spring locks with spring-loaded mechanism engage reliably even after years of jobsite abuse.

Working Heights	Measurement
Reach Height	19 ft
Max Safe Working Height	17 ft
Max Working Length	17 ft

Werner includes pre-pierced holes for field installation of accessories like pole lashes or cable hooks. Smart design choice — you can add the accessories you need without drilling into the rails and compromising the ladder’s structure. The rail shield brackets with molded end caps protect the fiberglass from dings when you’re loading and unloading.

At 40 pounds, this ladder demands respect. It’s built for contractors who prioritize safety and durability over portability. The fiberglass rails won’t conduct electricity, but they also won’t bend like aluminum when you’re hauling tools and materials up to roof level.

Frequently Asked Questions

Q: Can I use this ladder for roofing work?

A: Yes. Ensure the ladder extends at least 3 feet above the roofline if accessing a roof, and never stand on the top three rungs of an extension ladder. The 300 lb capacity handles you plus a tool belt and materials.

Q: How do I set up this ladder safely?

A: Place on firm, level ground. Use the 4-to-1 rule (1 foot out for every 4 feet of height). Extend fly section using the pulley. Ensure both gravity locks are securely engaged over a rung. Engage the swivel feet (pads for hard surfaces, spurs for soil/grass).

Q: Is this ladder suitable for homeowner use?

A: It’s overkill for basic homeowner tasks. The Type IA 300 lb rating and non-conductive fiberglass are designed for professional electrical and commercial work. Homeowners changing gutters would be fine with a lighter Type II ladder.

Q: How does this compare to aluminum extension ladders?

A: Aluminum extension ladders are lighter and often less expensive but hazardous for use near electrical wires. The weight penalty of fiberglass (40 lbs vs. roughly 30 lbs for similar aluminum) buys you electrical safety.
