Seeing better means tying better. This plain background plate also improves any fly photograph. The HMH profile plate has a machined delrin support body with brass fittings and a stainless steel rod. White plate adjusts side to side, front to back, and tilts to give optimum view of fly. The plate measures 6" square and the wire mount allows you to move it as much as 7 1/8" in back of the vise stem and 5 1/4" to the right of the stem. Fits on ANY 3/8" (standard in USA) vise stem.
