It may look like a standard stepladder, but it’s so much more than that. The MicroBurst® from Little Giant Ladder Systems® has features that are unique to this model of ladder.
With its patent-pending Stable Lock™ spreader system made from a high-strength steel alloy; the MicroBurst gives you the stability needed to complete any task with confidence. On a typical stepladder, the spreader bar is weak, allowing the ladder to “walk” or shift, but on Little Giant’s MicroBurst, the Stable Lock spreader is strong, allowing you to set up the ladder and work in confidence.
Made from lightweight, non-conductive fiberglass, the MicroBurst can safely be used in a variety of situations. The fiberglass rails fit neatly inside each other, creating a slim, 3.5” storage and carrying profile, making it easier than ever to carry or store your stepladder.
This ladder meets or exceeds all OSHA and ANSI standards, and is available with a Type IA rating to hold 300 lbs. and a Type IAA rating to hold 375 lbs. It can be purchased in a 3’, 4’, 6’ and 8’ sizes.

Size refers to the ANSI definition of length. ANSI states that the size is defined by the combined length of all rail sections, with a tolerance of +/-3” on each section. Note, this does not take into account any overlap between sliding sections like those on an extension or multi-purpose ladder. This can cause a disparity in the size of the ladder versus the actual height. To determine which ladder you need, Little Giant recommends you reference maximum reach height instead of size.
The terminology for ladder duty ratings, grades, and types can sometimes be confusing. The ladder's duty rating is the maximum safe load capacity of that ladder according to ANSI standards. There are 3 types of ratings that Little Giant offers:
Type I - Made to handle everyday projects. Has a load capacity of 250 lbs.
Type IA- Designed with durability and regular use in mind. Has a load capacity of 300 lbs.
Type IAA- Built for professional performance and rugged use. Has a load capacity of 375 lbs.
Ladder specifications can be confusing due to safety regulation requirements. According to ANSI (American National Standards Institute), the ladder size is defined as the total length of each section and does not account for overlap on extension ladders. As a result, the overlapping sections reduce the total length of the ladder. When purchasing any ladder customers should pay particular attention to the maximum reach to ensure the correct product for the job.
