High Quality: Our stroller hooks are made of strong aluminum alloy, which is durable, corrosion-resistant, and high-strength. Soft Sponge Wrapped Handle: The hook is wrapped with a layer of sponge, which increases friction so it is not easy to slip off. If you lift many shopping bags by hand with a hook, the sponge can also protect your hands. Easy to Use: The stroller clips have a spring-loaded bar that easily opens to attach in one simple motion. Easy to detach by pushing in the bar and unhooking. Size: 14 cm x 8 cm (5.5\" x 3.1\"). The foam-coated section is 2 cm (0.8\") in diameter. Each piece weighs 90 g (3.2 oz). The stroller carabiner can carry a maximum weight of up to 15 kg (33 lb). The maximum bar width/diameter it can clamp around is 3.5 cm (1.37\"). Multifunction: Our stroller hooks are perfect for your pram, pushchair, or stroller on any shopping trip, leisure activity, outing, or on your travels. The stroller clip can also be used with wheelchairs, mobility vehicles, bicycles, walkers, shopping carts, backpacks, and more.
