Enhanced 4-Tread Configuration Benefits

Improved Accessibility and Comfort

The four-tread design provides significantly enhanced accessibility compared to shorter ladder configurations, offering more gradual stepping progression that reduces the physical demands of pool entry and exit. Each additional tread reduces the stepping distance and provides an additional rest point, making pool access more comfortable for users of all ages and physical capabilities.

The extended configuration is particularly beneficial for elderly users who may require more gradual progression, children who may not have the reach for larger steps, and individuals with mobility limitations who benefit from additional stability points during the access process.

Enhanced Safety Through Progressive Steps

The additional tread provides an extra safety margin by offering more stable intermediate positions during pool access. Users can take their time at each level, ensuring secure footing and stable hand positioning before proceeding to the next step. This progressive approach significantly reduces the risk of rushed or unstable transitions that can lead to accidents.

The four-tread configuration also provides better options for emergency situations, offering more intermediate positions where users can stabilize themselves if they experience difficulty during pool access.

Premium AISI316 Marine-Grade Construction

Superior Stainless Steel Specification

The CM4/18 utilizes the highest quality grade AISI316 marine-grade stainless steel throughout its extended construction, ensuring exceptional performance and longevity even with the increased structural demands of the four-tread configuration. The premium material specification provides superior corrosion resistance while maintaining the structural integrity necessary for the extended ladder design.

AISI316 stainless steel’s exceptional resistance to chloride attack, pitting corrosion, and stress corrosion cracking ensures that the extended ladder structure maintains its performance and appearance throughout decades of service, even under demanding pool chemical environments.

Robust Structural Engineering for Extended Configuration

The CM4/18 utilizes substantial 43mm (1.7″) diameter stainless steel tubing, providing the enhanced structural integrity necessary to support the additional tread while maintaining optimal stability and safety performance. The robust construction ensures that the extended configuration doesn’t compromise structural rigidity or introduce unwanted flexing under load.

The extended design requires careful engineering to maintain optimal proportions and structural performance, with reinforced connection points and enhanced mounting systems to accommodate the additional structural demands of the fourth tread.

Advanced Safety and Performance Features

Premium Anti-Slip Tread Technology

The CM4/18 incorporates Certikin’s advanced stainless steel anti-slip tread technology across all four stepping surfaces, providing consistent grip and stability throughout the extended access sequence. The uniform anti-slip performance across all treads ensures that users experience consistent safety characteristics regardless of which tread they’re using.

The engineered tread surface features precisely designed texture patterns that maximize grip while maintaining the smooth, easy-to-clean characteristics essential for pool maintenance. The anti-slip treatment is integral to the stainless steel material, ensuring consistent performance throughout the ladder’s extended service life.

Enhanced Structural Stability

The four-tread configuration actually enhances overall ladder stability by distributing user loads across more contact points and providing additional structural triangulation. The extended design creates a more stable platform that users can feel and trust, particularly important when the ladder is being used by multiple people or under demanding usage conditions.

The additional tread also provides more options for secure hand and foot placement, allowing users to maintain three-point contact more easily throughout their pool access sequence.

Advanced Pinch Anchor System

Enhanced Mounting for Extended Configuration
