  • Patent number: 6895838
    Abstract: A strainer lock apparatus for installing and removing a stainer in a sink or tub. A first member having a top end with a locking mechanism that may include a slot is inserted in the apertures of the strainer and rotated thus locking the first member which then hangs freely from the cross members. A second member with a threaded lock attached thereto is placed over the first member. A portion of the bottom end of the first member extends past the bottom end of the second member. An end piece is attached to the extended portion of the first member, thereby preventing the second member from falling from the first member. The second member and lock are brought into contact with the threaded surface of the top retainer section and rotated around the first member.
