Once the bottom seam is even near the cove, the liner is ready to be secured. This material is held in place through the use of coping strips prior to putting the top rails back onto the pool. Measure twice, buy once – whether installing for the first time, or replacing an existing liner, the solid blue pattern offers durability while not breaking the bank.
