Claims31
A corner piece for forming a corner of a pool, said corner piece comprising:
- a first substantially linear portion;
- a second substantially linear portion;
- wherein a projected tangent line of said first portion intersects with a projected tangent line of said second portion at an angle;
- a third portion comprising a liner receptor slot for receiving a pool liner wherein said third portion comprises a non-curved portion therein;
- wherein a tangential projection off of a first end of said third portion intersects said tangent line of said first portion at a first acute angle;
- and
- wherein a tangential projection off of a second end of said third portion intersects said tangent line of said second portion at a second acute angle.
