For daily commercial use, you need ANSI Type IA (300 lb) or Type IAA (375 lb) duty rating. Type IA is the standard for most contractors; Type IAA is recommended for crews regularly carrying heavy tools or materials up the ladder. Avoid Type II (225 lb) and Type III (200 lb) — those are homeowner ratings and don't hold up to daily jobsite use. Tool Mart stocks Type IA and IAA exclusively from Werner and Little Giant.

Always, when there's any possibility of contact with live electrical components. Aluminum conducts electricity; fiberglass does not. OSHA and most jurisdictions require fiberglass ladders for electrical work, and most electrical contractors mandate fiberglass company-wide regardless of the specific job. Werner's D6200 and 6100 series are the industry-standard fiberglass extension and step ladders.

For mobile contractors, cordless LED work lights have largely replaced corded halogen. They run cooler (no burn risk near insulation), produce more usable lumens per watt, last 10x longer in lifespan, and don't need a power source. The trade-off is runtime — most cordless lights run 4-10 hours per charge on standard batteries. Milwaukee M18 and DeWALT 20V MAX lights run on the same batteries as your drills, which is the main practical advantage.
