Draw bar springs are a type of extension spring which is incorporated between two loops of a wire.

The extension spring, under excessive deflection, faces a failure. In this situation, draw bar springs are used as they can withstand excessive deflection and also minimize buckling. One of the key features of draw bar springs is they have a fixed stop when the spring goes solid, thereby eliminating overstretching.

Some applications of a draw bar spring include porch swings or tensioning applications such as fences or gates.
