Little Giant Safety M17 17′ 1AA 375# Multi-Position Ladder

Description

Working on uneven plant floors becomes routine with the Little Giant Safety M17 Ladder. This multi-position tool shifts into twenty-four distinct setups, functioning as an A-frame, extension, or 90-degree ladder. The wide-flared base provides incredible footing on rough terrain. Hinge adjustment requires two hands, which slows down quick height changes compared to standard stepladders.

Cold-formed aerospace-grade aluminum alloy tubes make up the inner and outer stile assemblies. Heavy-duty cast aluminum Rock Lock adjusters grip the rungs using spring-loaded pins. Dual-pin cast steel hinge blocks provide rigid lock positions at several working angles. The ladder weighs 34 lbs bare, standing 55 inches high in storage mode and extending out to 15 feet total.

Key Features of Little Giant 10402

General maintenance technicians buy Little Giant 10402 ladders to tackle awkward stairwells and elevated plant machinery. This commercial multi-position frame replaces separate stepladders and extension units on industrial job sites.

• Rock Lock adjusters let you change ladder height quickly with simple palm pressure.
• Heavy-duty steel hinge joints click into place to form self-supporting A-frames or extension units.
• Flared aluminum legs provide wide base stance to prevent rollover during high-reach tasks.
• Staircase configuration levels the ladder legs securely on interior or exterior steps.
• Wide knurled rungs provide sure footing and relieve sole strain during long standing jobs.
• Non-conductive rubber shoes bite into slick concrete and protect finished hardwood floors.
• High-strength aerospace aluminum frame supports 375 lbs of worker tools and gear.

Hinge Strength And Torsional Test

Tested as an eight-foot A-frame, the ladder deflected 0.28 inches under a 375-lb test load. As an extension unit, the steel hinge system resisted rotational twist with sixty foot-pounds of torque applied. Rock Lock pins engage with twenty pounds of spring force, preventing accidental release. Aluminum outer stiles show zero distortion around the rung punchings.

Staircase Setup Realities And Limits

Adjusting the inner stiles on high stairs requires balance and attention to pin engagement. Do not buy this ladder for electrical utility pole work, live switchgear rooms, or high-voltage lines.

• Clear debris and loose gravel from the Rock Lock slider channels to prevent pin sticking.
• Check the steel hinge plates for dirt accumulation and spray with silicone lubricant.
• Inspect the rubber base feet for embedded sheet metal screws or deep tread cuts.
