Review on Zipbolt Angled Handrail To Newel Post Connector — 11.560 Angled Staircase Railbolt For Lower Connection Acute Angle Post Fastener, Easy Installation For Residential And Commercial Use — 5 Double Packs by Solomon Baron

While it seems like a good idea, only recommend for new construction. My original handrail was toe nailed to the newel post and came undone. I thought this would be the ticket, but realized once I bought it and opened it that once you screw the lag bolt end into the post, it would be impossible to get the other end into a hole drilled into end of handrail without ripping opposite end of handrail off wall, creating an entirely new problem. Would have liked to have this system work without creating a ton of new work for myself. With balusters and upstairs end of rail still intact, there was just enough play to push handrail away from post to do all the drilling, but not enough to make this thing fit into handrail hole.
