ABSTRACT:
A reinforcement pad for protecting a liner of a pool from damage caused by a user ascending and descending a pool ladder having two upper ends and two lower ends. The reinforcement pad has a substantially oval pad base and a substantially cylindrical socket extending therefrom. The socket, which has a centrally located bore, is mateable with only one lower ladder end. A user inserts one lower ladder end into the bore of the socket of one reinforcement pad. The user then repeats this step with the other lower ladder end and another reinforcement pad. Next, the user positions the pad base against the pool liner and attaches the upper ladder ends to the pool deck. The pad distributes pressure applied to the ladder over the wider area of the lower surface of the pad base, thereby preventing the liner from becoming damaged.
