The Vevor 8' round above ground pool liner is designed for steel-sided above-ground pools with wall heights up to 54 inches. Made from durable vinyl, it helps resist punctures, wear, and chlorine exposure for long-lasting outdoor use. Its soft, smooth surface adds a more comfortable feel underfoot while helping protect the pool interior. The overlap design allows for straightforward installation and secure placement on compatible round pools. It can also serve as a versatile waterproof liner for other outdoor covering needs.
