Uncompromising Safety and British Engineering
When working at height, compromising on equipment is simply not an option. The LFI PRo Extender Extension Ladders represent the pinnacle of British design, engineered specifically for maximum safety, comfort, and durability. Manufactured to the latest cutting-edge standards, these ladders meet the new improved strength and slip-tests outlined in BS EN131-2:2010 + A2:2017. Whether you are tackling heavy-duty commercial projects or rigorous industrial maintenance, the PRo Extender is built to deliver exceptional reliability day in and day out.
Technical Precision for the Professional
Every aspect of the LFI PRo Extender has been meticulously crafted to support the demands of modern trade professionals. The ladder features large 32mm serrated Trilobular rungs, which utilise a 3-way crimp and swage design for maximum durability and comfort when working at height. Crucially, these rungs are designed to orientate flat when the ladder is erected at the correct climbing angle, providing an incredibly stable and fatigue-reducing standing surface.
Further enhancing user safety, the base is fitted with deep serrated rubber feet for maximum grip on all surfaces. To ensure secure operation during extension and retraction, a heavy-duty galvanised steel locking catch comes as standard on all extension models.
