Children will have a whale of a time on Whale Climber. Realistic barnacles even help with climbing! The climber is designed for children ages 2 to 12 (18 months to 12 years CSA). Whale Climber can be used to access 5’ decks for ages 5 to 12. It’s made of GFRP (Glass Fiber Reinforced Polymer), which is much lighter and friendlier to the touch than Glass Fiber Reinforced Concrete products. Less weight means it’s easier to install and less costly to ship!
