Disclosed is a-stretcher bar frame and canvas fastening system. The system consists of side bars of variable lengths, pre-molded corners, and connecting segments for easy assembly and disassembly. The interlocking bar, corner, and connecting segments, features a locking mechanism utilizing the male plug and a female socket. The connecting segment plug-includes four resilient flexible arms with flat tooth surfaces that interlock during insertion into the bar or corner socket. The plug and socket members snap together for a tight and straight fit that is released using a side release mechanism. The side release mechanism disengages the stretcher bar segments by pressing inward on the flat tooth surfaces of the latching arms of the connecting segments. The back side of the stretcher bar features a self-healing canvas fastening block for insertion of staples and other fasteners allowing the canvas to be stretched or removed.

Disclosed is a stretcher bar framing and canvas fastening system specifically designed for artists. The stretcher bar framing system consists of side bar segments of variable lengths and pre-molded corner segments that are snap fitting and interlocking for quick and easy assembly and disassembly. The snap fit interlocking bar and corner segments feature a locking mechanism that utilizes a male plug member and a female socket member. The plug member includes a pair of resilient flexible arms with a flat surface tooth that interlocks when fully inserted in the socket member. The plug and socket members snap together for a tight and straight fit that can be quickly released using a side release mechanism. The side release mechanism disengages the stretcher bar segments by pressing inward on the flat tooth surface of the latching arms located within the side aperture on the bar. The back side of the stretcher bar features a self-healing canvas fastening block for insertion of tack fasteners or staples that allow a canvas to be mounted, re-stretched, removed, or remounted. The stretcher bar system features a museum quality depth that is affordable and does not require the need for additional framing. The stretcher bar is made of a low cost, light-weight, non-warping, durable plastic or resin material that provides structural durability, resiliency, and stability. The pre-molded corner allows for an exact square without using wedges for further adjustments.
