“Installing a Vertical Frame MATERIALS To construct a vertical frame, you need: two 5-foot electrical conduit pipes (1/2-inch diameter); one 4-foot conduit pipe (1/2-inch diameter); two 18-inch long rebar supports of 1/2-inch diameter; screwdriver; hammer; two elbow connectors; and trellis netting. ASSEMBLY Once you’ve attached the elbow connectors to your 4-foot conduit pipe, lay it against the north-facing board of your SFG. Next, hammer the rebar where the elbows are located. You’ll want to drive the rebar in about half its height. Slide the 5-foot conduit pipes over the rebar for a standard strength vertical frame. Or use a short steel fence post instead of the rebar for an extra-strong frame. Attach the top conduit to the legs and tighten the screws in the elbows.”
