A track structure for retaining the liner of a liner type in-ground swimming pool is comprised of two component parts including an elongated length of a channel-like body section adapted to be secured about the perimeter of a liner-type pool and a channel-like insert adapted to be removably disposed within the body section. Both components are formed of polymeric plastic composition and both are configured at least partially complementary, so as to enable the insert to effect a snap-in interfit for securing the insert within the body. The insert when disposed within the body cooperates with an internal body surface wall to define a narrow clearance through which the liner can extend while securing the beaded edge of the liner against withdrawal. When the body and insert are assembled, a single exposed channel is provided, enabling a form board to be positioned thereat for the pouring and setting of aggregate deciking about the pool. Also disclosed is the use of an adhesive tape having a detergent-soluble gum for mounting the form board directly onto the surface of an in-place linear. On retrieving the form board, any gum residue on the liner can be removed with a detergent solution.

A track for retaining the beaded edge of a swimming pool liner comprising: an elongated body section adapted for mounting about the perimeter of a swimming pool to be lined and having a channel-like sectional configuration orientated with its channel opening generally facing toward the pool; and insert means comprising a channel-like section removably insertable within said body section so as to be orientated with its channel opening generally facing toward the interior of the pool; said insert means being operative when disposed in said body section to cooperate with a body section surface thereat to define a relatively narrow clearance adapted for retaining a beaded edge of a pool liner against withdrawal while the channel opening of said insert means extends separated but substantially parallel to said clearance to be functionally independent of said liner retention and retains available for separate utilization.
