A plate designed for a TB-6 monitor arm can be adapted by drilling an additional hole to accommodate a backup LCD monitor
Several manufacturers have begun producing dedicated Steadicam monitor mounts that may offer compatibility with standard spigot threads
LCD monitor mounting accessories available through major video equipment retailers may provide ready-made solutions for attaching backup monitors to existing arm assemblies
