The 4" Step Riser Base for Royal Entrance Step is a simple yet essential accessory for enhancing the Royal Entrance step system in above-ground pools. By adding an extra 4” of height, this riser helps accommodate pools with deeper floors or taller walls, ensuring that the top step aligns comfortably with the pool's edge. Constructed from durable, UV-resistant polyethylene, it integrates seamlessly with the step base and maintains compatibility with key safety components such as ballast compartments and handrails. Installation is straightforward, making it a quick and effective upgrade for pool accessibility.
