The NXT1A10 Fiberglass 10-foot Step Ladder is ideal for any professional. With a duty rating of 300 pounds, it features a LOCKTOP® which provides maximum storage capacity for most frequently used tools and components. The LOCKTOP® features an impact driver slot to safely hold the #1 most used tool by professionals today. An anchor point allows for tools to be tethered to the top to prevent injuries and damages below from falling tools. The patented Lock-in system works with a full line of accessories which extends the usable space on the top. Fiberglass rails are non-conductive for working near electricity. The steps are fully braced and the back of the ladder has a full set of rear horizontals which provides durability and stability. The EDGE bracing system helps protect the rails from damage. The NXT1A10 incorporates a wider base than code requires which provides tip resistance pros depend on.
