A frame for supporting a pressure relief valve located within a frac line connected to high pressure pumps on frac trucks. A metallic base is formed from rectangular tubing in the shape of a box. Saddles on the base support a tee on the lower portion of the relief valve. Brace links are connected at one end to the corners of the metallic base and swivel about clevises to allow access to the pressure relief valve. The other end of the brace links connect to clevises on a flange when assembled. The flange is rigidly connected to an upper portion of the relief valve to stabilize the assembly. Lifting loops on the flange allow the frame to be lifted during assembly.
