Same problem as the short rail: you can't get behind the wall, and you need a solid grip point that doesn't rely on a through-bolt. The Jaycar MHE832 gives you 455 mm of 316 stainless steel rail with welded mounting feet that take countersunk No. 10 screws from the top only. The 50 mm stand-off is just enough to get your whole hand under the rail without your wrist pressing into the surface. Welded, not bolted-on brackets, so there's nothing to back off after a season of salt air or site dust. Drop it on, drill two holes, tighten, walk away
